Your brother is dead on and his anger at the other guys makes sense to me
It’s like a nutjob lone gunman.
That doesn’t really mean anything other than a guy was mentally ill, but when a bunch of dudes stand around in broad daylight while people film them like it’s a normal day, it obviously begs the question what do these motherfuckers do at 3am with a guy talking back and resisting a bit and no crowd?
A lone psychopath might have found out his wife was divorcing him that morning or something and went off, but all those dudes just chilling...
