I have a potential scenario that I've had some questions on. I'm unsure on a few aspects of the law on assault and battery in Pennsylvania. Here are the specifics:
Say that a legal adult (18 years of age) would provoke a fight with a minor who is 17 on school property. The 18 year old has a record and served time in a juvinile facility in the past for that. Assuming he hit the 17 year old first and he is an adult, what would the potential for punishment be in Pennsylvania? Would the circumstances be different off of school property? Would the situation change depending on what words were exchanged (i.e. an arguement)?
Another aspect of this I'm curious about is if the 17 year old swung back at the adult in his defense would the 17 year old be at fault or liable for any fine? I've been told that a $400 fine is associated with involvement in any fight, though I'd like to know how true that statement is. Logically I would not think that someone trying to defend themselves in a fight begun by someone else would be at any fault but I would just like some clarification.
Thank you very much for your help!
