I bet you have a past record of being in trouble and being dishonest, untrustworthy? This is what usually happens. First you need to stay far away from any trouble, drama. Don't get involved, don't ask questions, don't even stand near the situation. You will become part of it, even if you are innocent, based on your reputation. You have to regain respect and trust back, long hard road! Good luck! Stay away from the troublemakers, they aren't funny, and YOU are going to get in trouble, guilty or not!
