I know there wasn't a threat. at least a real one. Only a perceived one that he didn't perceive when he unlocked door to go outside... which suddenly was created (in his head, mind you) the minute the silhouette didn't obey him.
legalize it. Make it 100% legal to shoot anyone in the dark, that doesn't listen to you. Bad idea, right?
You can't say this is okay. not even once. Charge him and give him a suspended sentence. but you do realize this dude is STILL packing heat, right? He still has ability to scream orders at unknown people then shoot bullets at them, should they disobey some noble power he believes he has.
Sorry shockwave, but you sure as SHIT wouldn't want this cowboy as your next door neighbor. Would you? Yes or no.
