Problem
You are a police chief and one of your officers just caught a serial rapist that has been terrorizing the community. The suspect's DNA matches biological evidence already collected. There is great relief in the city. You ask the officer (whom you know very well) how he found the offender. The officer pulls you aside and says, "I thought it might be him, so I planted a bug in his house and overheard him bragging to his scumbag friends." The listening device was not authorized with a search warrant. What do you do?
