it's kind of weird the first thing I notice is that someone else was recording him from a different angle on how he shot that drone down! 2nd the reporter says that there is a drone shot on his own website! So it may be that he did rhis for his own publicity.... it hard to believe this story!
Too many cameras handy for this to be true. If this really is a publicity stunt, I don't think he want to be remembered for waving around a shotgun in an irrational way. Not sure I'd want to do business with him.
Great, now may got people making up stories involving drones for their own publicity stunts. Don't fall for it guys. Unfortunately a lot of people will.
