Who does that, other than on TV crime shows? Ask a cop to dust for fingerprints when your house is broken into and see what the reaction is (besides uproarious laughter). Matching ballistics? Please...
I dunno, I've had them dust without request because they were investigating a string of crimes. (nothing ever came of it that I know of)
On a related note, somebody doesnt learn from his mistakes.
Headed north on 69 and saw a guy on a brand new (to him at least, paper plates) 1100cc crotch rocket pulled over getting a ticket just north of the 37 exit in Fishers.
I was keeping up with traffic, so obviously I was not following the posted limit. I hit all the green lights until I got to the turn off to go to Cabelas. As I am sitting at the red light, I look over and see that same guy, sitting at the far end of the line waiting for the red light too.
So he gets a ticket, and immediately goes WELL over the speed limit again to manage to catch up to me with a significant head start. Damn, son. How do you ride that thing with balls that big?
