high tech tools for the LAPD

Stick It To 'Em

I guess this is a good use of technology. Apparently the LAPD will be able to shoot a dart at cars that transmits a GPS signal through an encrypted cellular channel so they can aprehend vehicles without the dangerous chase. The computer will just track the car and allow for a calmer arrest.

I wonder what type of warrent system they'll need to shoot one at a car? Can they shoot one at your car to track you because you were speeding, or ran a red light? Then just stop and pick you up later when you stop by the grocery store?
