Unless he goes looking for trouble he will be fine and I mean if he was to come around certain faces and show of in front of certain people he could have a problem.

No one will hit him in this day and age unless he literally goes up to these guys

I think it was scars who said unless he came face to face with two or more mobsters no one will do anything the only reason they would do something if it came face to face is because they have there rep and people would say why didn't you do anything. If the guy avoids certain areas he is fine
