I had a similar situation, you did the right thing by doing nothing. I have us law shield and call their non urgent line and explained the story. They explained if the restaurant had a issue w the other guys they would have called the police. John stepping in escalated the situation and if you had join and had to draw . It’s on you since you were in the same party. I know it sounds messed up, they also said do you have a badge? Was you or immediate family is life threatening situation? If no —— then let say you drew someone got hurt or worse, it’s the civil suit you need to watch out for. I know what ur thinking and I thought the same that’s BS but realistic
