Naaahhhhh.

Replace the Po-Lice chopper with an A-10.

MUCH more satisfying...

I think this gizmo will work as a way to find bad guys who somehow "get away" during a chase - but it won't eliminate the need for officers to stay behind the suspect and do exactly what they're doing now.

If they change policy and rely on the gizmo, that's an opportunity to play games with the device.

However, if nothing changes from current chase policy and there's still a black/white on the suspect's bumper, and a chopper following his every move, then the gizmo would allow the suspect to be re-acquired if they somehow shook off the pursuing officers.

So it's probably useful, but shouldn't cause a change in the chase policy. That's way over-reacting.
