Thread: NYPD researching technology to detect concealed weapons

What the....???

NYC Police Pursuing Technology To Scan Pedestrians For Guns | Fox News

The New York Police Department is working with the Department of Defense to further crack down on illegal guns in the city by researching technology that could detect concealed weapons on people as they walk down the street.

Infrared rays would scan a “form of radiation emitted from the body” on a person carrying a gun on the city’s streets, New York Police Commissioner Raymond Kelly said Tuesday at a State of the NYPD event, the New York Post reports.

The technology, known as terahertz imaging detection, works on the basis that the rays cannot pass through metal, thereby creating a digital outline of where a gun is hiding on someone. And it can measure energy radiating off a body from up to 16 feet away, CBS New York reports.

Kelly told the audience that the scanner would be used only when reasonable suspicious circumstances called for it and could decrease the instances of stop-and-frisks on the street, according to the TV station.

But the news also has raised privacy concerns.

“It’s worrisome. It implicates privacy, the right to walk down the street without being subjected to a virtual pat-down by the Police Department when you’re doing nothing wrong,” the New York Civil Liberties Union's Donna Lieberman told CBS New York.

The Post reports the scanners would be mounted on NYPD vans, with the rays aiming at people on the street.

So much for illegal searches.

I guess this doesn't mean a thing anymore:
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

right next to the right to keep and bear arms!

Hm. DC is probably frothing at the bit to get hold of this tech.

This is one of the instances I hope the ACLU steps in and bubblegumslaps the NYPD and the City of New York for trying this kind of crap.

Maybe they too can bust that 17 year old chick that caused the TSA so much grief with her gun design on the purse.

Next hot item for sale in NYC - metal lined jackets.

And people thought my tinfoil suit wouldn't be useful.

Hmmm. All jackets must be lined with metalized Mylar. Hmmm.

Who wants to go to Nuh Yawk, anyway?

Exactly!

Not me.

After all this, its still not going to stop criminals.. /facepalm

I work in a terahertz spectroscopy lab. In order to detect a terahertz (THz) photon we have to cool a bolometer (detector) down to around 40 Kelvin so we can detect phonons (vibrations) in a silicon detector. We also golay cell (we have one on loan) might be the answer, but they are freaking fragile and hate being vibrated. Any THz measuring apparatus will be cumbersome at best, good room-temperature detectors are still a few years out. All THz detectors hate being vibrated, you have to wait a long time for them to settle (2-3min) after moving them at anything faster than a snails pace. They'd have to have some wicked system for keeping the detection element still while driving and scanning.

Mylar works great for blocking and it's light weight. We use it in a Michelson interferometer to characterize our THz pulses. A single layer will block about 1/2 the THz you give off, so layer up (3 or 4 layers ought to do it).

And yes, criminals will keep being bad. Disarming the populace and illegally searching them (whether with pat-downs or THz detection) is moronic at best. This isn't England after all.

All these things are not laid out to stop criminals. Heat/sound weapons, these sensors, gun/sound mapping/sensors; all of these things are for the government to combat you, the terrorist.

The government knows a massive economic collapse is coming which will result in uprisings, riots, civil unrest. All of these technologies are already developed or on the drawing board to fight YOU.

Sorry deluded people who thought the 'war on terror' was about fighting some brown people 2500 miles away. It is really a war on freedom, a war against YOU. Abdulla, thousands of miles away, doesn't care a less whether you have 'freedoms' or not nor does he care about taking any of them away.

The technology is nothing new. It is FLIR, ie: foreward looking infrared. It can see temperature changes as images and differentiate closer than a half degree. You can follow a truck down the road from an aircraft and tell if it is overloaded by the heat signature on the road from the tires. A jackrabbit looks like a spotlight from 2 miles up. The police can follow a perps footprints as they run through yards at night. It can detect inflamed parts of the body, and it will sillouette any object under your cloths that varys from your body temp.
The safire system can even be locked to a weapons system and it does not miss, day or night. No new technology here. They just want you to think that it is. IR has alread received some unconstitutional use definitions and they just want you to think this is something that is other than what it is.
