Yeah, I think that story had a pretty good ending. The robber's parents need to STFU and be thankful that their dumbass son didn't die from the gunshot. Hopefully, he will do his time and learn his lesson from this, but not likely.
Good thing the guy who fired the shot was there at the time. He stopped an armed robbery in progress and may have saved that store employee's life. Absolutely nothing wrong with that. If I were in that situation, I would've done the same thing.
