Look, I’m one of the first to say Americans are dangerously obsessed with firearms, but this wasn’t a firearms issue - it was straight up murder. This wasn’t an attempt to teach with any sort of responsibility or following any safety at all. If anyone tried to teach my kids firearm safety by sticking the barrel in their chest they would be decked.
First rule - every firearm is loaded. Every. Fucking. Firearm. Is. Loaded.
