I just don't understand what ANYONE is going to do even if they do find him. He can defend himself just like anyone else in a confrontation, usually with a firearm if he's a drug dealer... and on top of that, HE WILL HAVE THE LAW ON HIS SIDE! He can call the cops saying these thugs are hassling me. What is anyone going to do? Say, well officer, he stole my drugs so my friends here just roughed him up... GET REAL! He will win any confrontation in the courts AND with LE coming to any scene.
This entire thread has gotten into a ridiculous circus with people thinking they are bounty hunters.
Edit: Have you ever seen the scene where someone actually confronted another person at their front door? I have... and the guy was shot to death, with the homeowner walking away with his freedom as he was able to tell the police that this guy confronted him at his doorstep.
Stop acting silly guys.
