NYPD Takes Delivery of Dodge Hemi Chargers

NYPD Charger

The NYPD is finially starting to realize that those wimpy front wheel drive Impala and Malibu RMPs (radio mobile patrols) just don’t cut the mustard when it comes to rolling up at a no-holds-barred old school style po-lice testosterone party. According to AMNY:

Police Commissioner Ray Kelly announced Monday the department would be testing 15 flashy new 2006 Dodge Chargers on regular patrols, giving the NYPD a new top speed of 150 mph. The cars go from 0 to 60 in 6.5 seconds and stop much faster than NYPD’s current fleet of Chevrolet Impalas and Ford Crown Victorias, which max out at 110 mph.

They also get better gas mileage than the Crown Vic.

“We’re looking to diversify,” said Kelly, who suggested the new cars would be ordered by the hundreds to supplement the 3,000 cars and vans that bear the NYPD insignia. The Impalas and Crown Vics will remain in service throughout the city.

The 340 horsepower monsters will pack Hemi V-8s, stability control systems (which can be disabled on the fly for some real tire-smokin’ pedestrian-jeopardizin’ fun!), and something (a dimmer switch?) that disables the interior lights. Starting price: $29,000 bare. Look for some fancy strobe packages to make these really slick. If dressed up right these would make great highway interceptors but the last thing the NYPD needs on surface streets is to go faster.

Explosives Detection R & D

Posted by Jamie on 14 Aug 2006 | Tagged as: Aviation, Counterterrorism, Homeland Security, Law Enforcement, Research and Development

This is lifted directly from this post over at Homeland Security Watch.

The foiled UK terror plot has prompted the media to reexamine the Department of Homeland Security’s efforts to develop new explosive detection technologies over the past few years. The AP has a detailed story today that looks closely at this history:

As the British terror plot was unfolding, the Bush administration quietly tried to take away $6 million that was supposed to be spent this year developing new explosives detection technology. Congressional leaders rejected the idea, the latest in a series of Homeland Security Department steps that have left lawmakers and some of the department’s own experts questioning the commitment to create better anti-terror technologies.

The $6 million refers to a recent attempt by DHS to reprogram funds to the Federal Protective Service, which faces a $42 million budget shortfall in the current fiscal year. Later, the story notes:

The department failed to spend $200 million in research and development money from past years, forcing lawmakers to rescind the money this summer.

The phrase “forcing lawmakers to rescind” is a bit facetious. While it’s true that DHS S&T’s performance has been problematic in many respects, nobody forced Congress to rescind this money during the FY 2007 appropriations process. Congress made a deliberate decision to increase funds for state & local grant programs by raiding S&T’s budget last month. As I noted several weeks ago, “The increases in funds for these programs are made by increasing a rescission to DHS’s FY ‘06 science & technology budget and cutting the DHS management budget respectively - both questionable judgments, in my opinion.”

Later, the article refers to a technology deployed at Narita Airport in Japan to detect liquid explosives:

The administration also was slow to start testing a new liquid explosives detector that the Japanese government provided to the United States earlier this year.

The British plot to blow up as many as 10 American airlines on trans-Atlantic flights would have involved liquid explosives.

Hawley said Homeland Security is now going to test the detector in six American airports. “It is very promising technology, and we are extremely interested in it to help us operationally in the next several years,” he said.

Japan has been using the liquid explosive detectors in its Narita International Airport in Tokyo and demonstrated the technology to U.S. officials at a conference in January, the Japanese Embassy in Washington said.

This is likely most promising option available in the near-term, and hopefully TSA will accelerate their efforts to field-test it. And DHS S&T should undertake an immediate, comprehensive review of existing technologies and provide targeted seed funding to companies or research labs that have promising technologies which can remedy the system’s vulnerabilities.

911 Callers Will Soon Be Able to Send Cameraphone Photos to Dispatchers

Posted by Jamie on 11 Aug 2006 | Tagged as: Geographic Information Systems, Telecommunications

cachcell.jpgAs if 911 dispatchers and call-takers weren’t already overwhelmed by increasing call volumes, staffing and training issues, and a general “fog of war” approach to system status management Florida’s PowerPhone has announced software that promises to ad a new type of data to handle, images.

The system capitalizes on the 370.5 million cameraphones in use today–50% of those in use everall–a number that promises to increase to nearly 87% of all cellular phones in use by 2010. PowerPhone’s Computer Aided Call Handling software package can enable callers to send pictures from their camera-enabled handsets to dispatchers who then log them and forward information to responders.

PowerPhone’s CPD system works like this: a citizen calls from his cell phone to report an emergency or suspicious activity—let’s say he’s spotted a missing child who the police issued an Amber Alert for. The caller dials 9-1-1 to report the sighting and says he can send a picture of the child for verification. The call handler sends an e-mail message to the caller’s cell phone from PowerPhone’s Total Response® Computer Aided Call Handlingâ„¢ software. The caller then replies to this message with the photo attached. Total Response stores the photo in the incident record for easy reference.

By following this process, the 9-1-1 center ensures that photos are linked with the appropriate records of the citizen’s 9-1-1 call. Even more important, this process discourages citizens from randomly sending photos into the 9-1-1 center-an arrangement that can lead to pranks and other abuses of the system.

As with any new implementation there are several potential benefits and stumbling points to note:

  • The ability to forward immediate images of suspects, vehicles, license plates, even call locations to responders could prove invaluable. It could mean the difference between finding a location and not in some situations.
  • The increase in data that will have to be handled by the dispatchers and dispatching systems could prove immense. As camera resolution increases so does the file size of images and video clips. Additionally, the more the community becomes aware of this technology, the more data must be sifted through and tagged which requires a robust and secure cataloguing and file-management system.
  • Errors and delays in data transmission could slow or complicate responses if users become dependant.
  • This could be integrated with a comprehensive data reporting and management system for responders that would allow smooth transmission of image data from eyewitness to trauma room.
  • If this could work both ways dispatchers could forward detailed image or video-based prearrival instructions to callers who are called on to perform CPR or other lifesaving interventions.
  • Early adoption of these types of technologies would help pave the way for emerging ones by providing infrastructure and hands-on proof-of-concept.
  • If developed the images could be tagged with geographical information such as GPS coordinates or tie in with other location-based 911 systems like those from Verizon.

HAZARD - Acetone Peroxide Explosives and Drug Detection Kits

Posted by Jamie on 11 Aug 2006 | Tagged as: Counterterrorism, HazMat, Homeland Security, Law Enforcement

tatp.jpgAcetone peroxide explosives, as we discussed yesterday, present numerous challenges to responders when considering the difficulty of detecting and identifying not only the explosives but their component chemicals in the field. This threat is highlighted by recent evidence that focuses on an alleged terror plot to bring down commercial airliners with separate component chemicals that, when combined, would create a volatile liquid explosive. U.S. and British government sources have confirmed since our posting yesterday that the evidence found points toward the possibility of TATP or other acetone peroxide based explosives being used in future attacks, a fact that doesn’t suprise leading counterterrorism experts.

An alert the FBI and DHS sent out Thursday to state and local law enforcement agencies — which is classified “For Official Use Only” and was obtained by TIME — warns them that the peroxide-based explosives could also be employed in future attacks here. . .

The FBI-DHS report next warns law enforcement agencies about the two peroxide-based liquid explosive that could be used in a future attack against the U.S.–triacetone triperoxide (TATP) or hexamethylene triperoxide diamine (HMTD). The report describes how a terrorist would assemble bombs with these chemicals. Peroxide-based liquid explosives “are sensitive to heat, shock, and friction, can be initiated simply with fire or electrical charge, and can also be used to produce improvised detonators,” the report states. “For example, TATP or HMTD may be placed in a tube or syringe body in contact with a bare bulb filament, such as that obtained from inside a Christmas tree light bulb, to produce an explosion.” The report doesn’t mention anything about a terrorist assembling such a bomb on a plane, but it does warn that manufacturing such a device can be dangerous for the bombmaker. “Because of the instability of these substances,” the report notes, “spontaneous detonation can occur during the production process.”

Obviously, as the technological expertise of terrorists increases, so must the technologies that we use to detect them and mitigate their effects.

meth1.jpgThe increased responder-level awareness of TATP and other explosives, as always, should lead to a higher index of suspicion when searching all suspects, not simply those suspected of terrorist activities. Keep in mind, however, that these hommade explosives are made in similar conditions and with similar chemicals as another law enforcement and hazardous materials concern–narotics. The manufacture and distribution of narcotics such as methamphetamines and crack cocaine has presented challenges for the LE community that have bred several technological solutions including chemical kits designed to test for the presence of illicit substances. Historically, officials have first relied on visual identification of suspected substances and have then deferred to these kits for confirmation and further identification.

The introduction of home made peroxide explosives to this equation creates a host of new, and very dangerous, problems as revealed in DHS documents from the Explosive Devices module (PDF 1.2MB) of the Awareness Level WMD Training Program . These explosives (when not in “liquid form”) often look like crack cocaine or methamphetamines but, “will react violently with drug field test kits.

fieldtests01.gifIn other words, if you confuse these substances in the field and attempt to use commonly available identification technologies (the ones that most officers use daily) to make a determination then you could lose important body parts or your life. Here’s the whole blurb on Peroxide Explosives from the manual:

Peroxide-based improvised explosives are an emerging threat domestically. However, these IED have been a common explosive used by international terrorists for some time.

Hexamethylenetriperoxidediamine (hex-a-meth-i-len-tri-per-ox-id-di-a-men) (HMTD) and Triacetonetriperoxide (tri-ass-e-ton-tri-per-ox-id) (TATP) were initially developed 100 years ago. They are both extremely sensitive and are used as an explosive by terrorists/bombers as both an initiator (blasting cap) and as a main charge. TATP is commonly found as the main charge being employed by Middle East terrorists in suicide bombings.

HMTD has between 60-116% of the power of TNT, and is comprised of peroxide (ideally 30% or above), citric acid, and hexamine (heat tabs). TATP has 88% of the power of TNT and is comprised of peroxide, acetone, and sulfuric (battery) acid.

WARNING: In dry form, HMTD and TATP could appear similar to crack cocaine. These explosives will react violently with drug field test kits. Individuals should consider, and look for, any indicators present on a drug scene that may also be indicators of explosive manufacture — this is becoming more common. If so, the investigator should consider marking the evidence as a possible explosive and sending it to their lab for testing. HMTD and TATP are ideal as explosives for improvised blasting caps, and were originally developed for such use.

The documents don’t say much after that ominous warning and a bit of internet digging didn’t turn up much either. The caveat here is when multiple detection technologies intersect there can be problems that one would not associate with either one. In this case, the detection regime for one substance can lead to disasterous results when you imagine a scenario where an IED lab is mistaken for a methamphetamine lab.

Acetone Peroxide Explosive Detection Technologies

Posted by Jamie on 10 Aug 2006 | Tagged as: Counterterrorism, Homeland Security, Law Enforcement, Research and Development

Acetone_peroxide.jpgBritish law enforcement officials have arrested 24 suspects in connection with a terrorist plot to smuggle and detonate a “binary explosive” that would be inert while in its separate parts but would become highly explosive when they are combined. If the whole concept sounds a bit “big bomb on the boat in Die Hard: With a Vengeance” to you then you’re not alone.

A senior congressional source said it is believed the plotters planned to mix a British sports drink with a gel-like substance to make an explosive that they would possibly trigger with an MP3 player or cell phone.

The sports drink could be combined with a peroxide-based paste to form a potent “explosive cocktail,” if properly done, said a U.S. counterterrorism official.

“There are strong reasons to believe the materials in a beverage like that could have been part of the formula,” the official said.

The media reports that the explosive they planned to use was some type of acetone peroxide explosive like TATP. TATP is highly volitile and is often called the “Mother of Satan” and the “suicide bomber’s explosive of choice” because, much like all acetone peroxide explosives, it is relatively easy to manufacture using household chemicals and it is extremely difficult to detect.

First discovered in 1980 in Hebron, TATP is made by mixing hydrogen peroxide, which can be bought in disinfectant form at the neighborhood pharmacy, and acetone, commonly found in paint thinners. The compound is helped along by an acid catalyst. “The liquid from your car battery or even lemon juice will do the trick,” notes Keinan. The easy recipe is not lost on the bomb makers: In just one raid in 1998, Palestinian Authority security personnel uncovered 800 kilograms of TATP in a Nablus garage.

If operating personnel are trained to look for it, existing portable technologies — such as ion mobility spectrometry, which identifies an explosive by its molecular mass, and nuclear quadrupole resonance, which looks for signature radio frequencies — should theoretically be able to pick up TATP, contend advocates.

Acetone peroxide explosives were also the choice of “shoe bomber” Richard Reid (TAPT) and the July 7, 2005 terrorist attacks in London (HDMT) so they obviously present a growing problem for responders. The question is one of how we resasonably equip ourselves to detect the explosves and the chemicals used to cook it up.

explosivetester.jpgDespite numerous advances in detection technology in the last few years especially with the deluge of research and development funds coming from the U.S. and other goverment antiterrorism initiatives common design hurdles remain: training, utilization, and portability. Some recent advances in the detection of TATP type explosives such as Ehud Keinan’s pen-sized Peroxide Explosives Detector offer a new paradigm of portability to airport screeners and other law enforcement officers; this design, however, requires that the device be touching the person who is being screened so they aren’t effective in crowded situations like subway stations and large events. They are, however, effective when used in one-on-one physical searches–you know, the kind the TSA just loves to perform.
