So... you spent ten minutes scared, in a pig pile with some naked strippers, and eventually came out not only with the $200 that you lost, but also a $750 bonus. Now, because of something a cop said, you want to risk breaking probation to teach someone a lesson about something that happened nearly a decade ago?
I'd say that if you see dude again, you should straight up ask him, point blank, what happened. If you're not satisfied with the answer, break his nose and tell him he better leave town. Then go on living your grown man life, while other dude lives scared, relocates, and continues to be a shitbag.
Or, you could stew about until next time you see him, beat him with a crowbar, take a "trophy", and then have the satisfaction of knowing that a bunch of internet dirtbags have your back when you go to jail or some of his other friends decide to come by your crib again.
