If you were jogging in a some neighborhood and someone has a gun and telling you to stay put until the cops arrive, would you charge the person with the gun and attempt to disarm them?
“Did he think they were going to kill him?”
Would you? Maybe they were trying to give him a Watchtower.
C'mon, these were typical neighborhood types, not gangsters. If the decedent thought for one second they'd shoot him if he attempted to disarm one of them he'd would have taken off for the tall grass. Anyone in that situation, people with guns out, not in the hood, would have said, call the cops, be my guest, I'll wait right here. Not charge armed people. You'd have to be a lunatic or very desperate to charge an armed person like he did.
Btw, to be clear, these people apparently should have known better than get get directly involved over some guy poking around a home construction site. They should have hung way back, followed at a distance if they felt it was necessary, and just called the cops.
That being said, the jogger running towards the gunman and then attacking and attempting to disarm a man holding a gun is not a reasonable, expected or a normal response to people obviously suspecting you of something, and wanting you to stay put for the cops. What would you do if someone suspected you of shoplifting at bozomart? Attack them?
