It is not what you think it is, but the idea behind it is actually pretty clever. Police car chases are scary things that put people in danger. Not only do you have the reckless driver but you have a swarm of police cars in pursuit.
No, the cannon does not destroy the car a la Green Hornet or Mad max. It shoots out a sticky GPS cannonball which allows the police to eventually locate the car smartly.
It is being tested in Iowa, Arizona, Texas and Florida and the 'cannonballs' cost $250 apiece.
It will be interesting to see what Fourth Amendment issues come from this, and some point out that planting a GPS device on a vehicle has typically meant getting a warrant. the manufacturer says it will be okay,
