I'm not up to going head to head with a thug anymore. But I would have had to help. Theres a reason I carry a head knocker beside the seat right next to a Glock 23. And if I'm in my truck theres another longer head knocker in the ledge between the cab and toolbox.
Sounds like a good combination.
Once they got her on the ground and started stomping her, it went lethal force. There's bound to have been a man in that traffic that was close enough to put it in park and lend first aid by way of a head knocker.
