Normally these discussions get framed in terms of "rights" and how the FBI are violating them, but the average person doesn't care a lot about their abstract rights. It doesn't register. The real issue, and what bothers me, and I think the FBI here don't "get", is that when they pull these stunts, they are helping the real criminals. In court, when someone who is actually guilty of a crime can show that the FBI did this sort of stunt, they can often appeal and nullify the entire sentence. Criminals can end up going free because the law enforcement felt it had a right to do whatever they wanted. When law enforcement acts in disregard to the law, they are not only breaking it, but aiding the real criminals escape justice.
