The reason isn't to save money. That's the pretext. The reason is to use state power to fuck the weak by avoiding the constitutional protections afforded all defendants in criminal cases. Any good defense attorney should know that.
this could help, cops could get fired for too many bs arrest, court doc.s could show repete cop offenders, also people will get pissed haveing to go through jury ''stuff'' and seeing what ''our'' state is wasting ''our'' money on.
