The world is full of idiots.
They needed the butt chewing you gave and probably more.
If they’re the only one who could potentially get hurt I wouldn’t have a problem with other people’s stupidity but they inevitably get other people hurt and that’s unforgivable.
There’s no such thing as an accident. Everything like this happens because of human error and negligence. Some of which is malicious some not. Neither are an excuse.
There’s not a single gun related injury that’s not 100% preventable. No different that DUI’s or STD’s.
Play dumb games. Win dumb prizes. The worst part is innocent bystanders getting a free door prize because some other idiots mistake.
