My question involves criminal law for the state of: PA
My son is 20. He went to a party (off campus) with his friends. Police came in (without asking for permission) and gave citations to everyone. No BAT was given. There were beers in the house. My son being under 21 was given citation (mailed to home). He didn't drink as he was just hanging out there - wrong place at the wrong time. I didn't realize this is a criminal offense. Plan to fight it in court. Any suggestion?
