If the passenger trying to help out the pilot was really arrested thats just plain stupid. He was trying to help the captain out and maybe the FO couldn't do anything anyway at least he would know what's wrong.
Thats almost like the FO yelling at me that I was breaking the law by being up while he was out of the cockpit. The captain rolled his eyes when the FO was yelling. I almost wanted to tell the dude to chill out and not to think everyone is out for you.
