Seems like he started the whole confrontation. He should have continued to phone the police until they resolved it or filed a complaint with them the next day. He was foolish to walk down there and demand that they quiet down.
Unfortunately this man has made his bed and now he must face the consequences. A CCW permit does not make you a police officer nor does it give you the right to unjustly shoot someone. He was a retired firefighter, I would have expected better restraint from him.
What an idiot...
