Since my girlfriend is pregnant, I would have handled the situation the same as his friend did. Regardless of the law, anyone shoving a pregnant girl out of the way for any reason needs to be dead. I wouldn't have needed a gun. I would have beat him to death. That's just the protective father/boyfriend instincts I have. And if any of the guy's friends wanted to join in, that's when the .40 would come out. "Responsible citizen" or not, anyone laying a hand on anyone I love can and will turn me into a citizen that just doesn't care how the law restricts certain actions to protect my family.
