A felon has recently broken out of prison. An civillian recognizes the man. Said civillian has a talent for electronics and manages to slip a homing transmitter on the felon's car. He then calls the cops on his cell-phone and tells them how to find the escapee.
Assuming they catch the guy, could the homing device get the case tossed out of court on a technicality (invasion of privacy, illegal surveillance or some such)? And how likely is this? CAN a civillian legally plant such a device? (And if not, how much trouble could he be in?)
