Fair question. He’s a known abusive asshole, which is now being called out publicly but really wasn’t before this happened. See Akay’s comment a little below mine, it’s 100% spot on. But basically by people playing in bands with him, booking those bands, and including him with the rest of the cool kids for various things, sent a message that how he was behaving was fine. I have no idea who he got the gun from, and I truly hope that it wasn’t given to him willingly. There are a lot of apologists in the scene for various bad behaviors and I don’t think they appreciate the consequences it can have.

Same here. It just sucks that the “scene” enables this kind of shithead behavior and it lead to this. Just absolutely horrible
