If you get arrested the best thing is if you are clearly wrong rather than innocent. Trying to defend yourself will only get you in four times more trouble. It appears Judges will through the book at people for having a trial by jury.
Plea Bargains are also given to criminals when they are caught red handed on video camera.
My adopted children's mom was murdered with a baseball bat by one of my son's biological father. He then knocked on my door at 8 AM but thankfully I was out of town with his biological son. He got 20 - 40 and can have parole in 16.
Then I have my friend accused by someone with zero evidence except a changing accusation over 9 months. He was offered 18 months I begged and even cried telling him to take the deal. "Why should I take the deal when I never did anything wrong?" 18 month plea became 12 YEARS!
