My son was recently at a mall and was waiting on his girlfriend so they could go eat and her shop. A security guard approached him and told him to leave because he was loitering. My son then made a comment not directly at the guard but to a friend with him. The security guard then became hostile and tried to intimidate my son and then told him he was banned from the mall.This is not the first time this guard has harassed my son and his friends. I have filed a harassment complaint against this guard and have yet to hear from management.What are my options?
