1: Law and Order: Equestrian Division (prosecutors on horses)
2: Violate the noise ordinance - listen to Manilow.
3: When you admit to committing adultery (in order to challenge a law you don't like) you can get prosecuted.
4: Prosecute them all - let God sort'em out. Or maybe just the people who vote you out of office.
5: No, you cannot just decide you are an attorney and undertake to defend someone charged with molestation.
6: Japan has revamped their criminal justice system so that each trial will have 3 professional and 6 lay judges to decide guilt or innocence and impose punishment. That's an interesting procedure. I wonder how it will work out in reality.
