Don't know how new this technology is, but many law enforcement agencies are using tazers to great effect.



Before, if someone attacked a police officer with a knife, the officers would have no choice but to shoot them with guns. Now, they have the option of using tazers, which are less lethal.

cops have this rocket powered thing on wheels that is located under the police car. during a car chase the cop can activate it and it will shoot out from under the cop car and will go under the car being chased. it has electrodes on it and will start shocking the car with high electrical current. it then messes up the electrical system of the car and shuts it down. then the car stops and the cops get the bad guy. i saw this on the discovery channel. its really cool. its not wide spread yet but will be. it decreases the lengh of a potentially dangerous high speed car chase
I don't know if this is considered technology but I got a speeding ticket in the mail for going 96 mph and wasn't even pulled over. I guess they have a helicopter that took my speed. This was new to me so maybe its new to you aswell. I don't have specific evidence but im sure you can find someWhat is a New Technology being used by law enforcement?
