Ontario, Canada cops are introducing what even they compare to the Batmobile's many gadgets --- a gun firing GPS-tracker bullets.

QuoteA small number of OPP vehicles are now equipped with a "GPS projecting launching system," Brad Blair, the deputy commissioner of traffic safety, announced at media conference.

"We're very excited about this," Blair said in an interview.

The projectiles are roughly the size of soup cans and are fired from the front grille of police vehicles.

One would hope that any fleeing suspect won't notice the thump of the impact from a soup-can-sized high-tech flying gummy-bear.
