You can throw out evidence gained based on a lie. Only one replier seemed to notice this.

Also, from what I understand perjury is more widespread than you might believe, and tends toward frequent fliers in court. As I understand it, some officers take the attitude "if they're going to lie, I'm not going to commit to always being honest, even if it means letting a POS out"

Don't agree, but just to address the point regarding cops being treated differently. People lie in court all the time, even getting caught red-handed and unprosecuted.

P.S. Regarding that police attitude toward lying, it's the same as any corruption: You might think prosecutors and cops pull out all the stops for the "real bad guys", and this may be partially true; however in reality, it just comes down to who pisses them off the most, which often doesn't have that much to do with whether someone is the worst of the worst.
