Hate to call attention to this, but I imagine once its adopted by NYPD, they'll be using it as justification to inspect any knives they see as well. Can't tell if its a gravity knife without a physical test, and a closer look will let them know if its a "dangerous knife" or not, even if it isn't a gravity knife.

Great, now thy want to give us all radiation even to my children I stroll down the street because guns are the problem for all the worlds crime and terrorism in NYC?!!! Give me a break!! That's the worst thing I've ever heard! It's bad enough TSA wants to do x-rays so they can see through clothing to your sexual genitalia to check for weapons? And that's gotta be healthy right? More cancer causing crap to help them do their danged jobs?!! I live in the NYC area and what they say is true, I have family that are in LE and they tell me the got quotas and some guys are beasts jus taking people down for collars or what not, trying to get overtime on their clocks, get raises, all in the scheme of helping themselves while under the cloak of "doing good" for society. I've had friends deal with actual robberies and gun related break ins, where the police were 20-30 mins late to the scene, but god forbid they pull a guy over for DUI the whole neighborhood task force is there to intimidate. They are no help, I'm not saying try are all bad but many abuse their power as they have throughout history of mankind since LE has been in existence. It's just another major flaw in society. Yes there are bad guys but you also need bad guys to catch em. All I'm saying is be fair, help society, dot abuse your power and earn your respect don't demand it because you wear a uniform. Because after you get out of work, you are a shmuck like any other shmuck on the street.
If you have nothing to hide you won't mind this light-stick up your backside...
