Surrounding and rocking your car (as these thugs or 'protesters' did in Ferguson and in Atlanta, where they also blocked I-75) is a threat of bodily harm, and is lawful cause to use deadly force.

These punks surround and rock my truck, they're going to be in a world of hurt. I will defend myself and my family with appropriate force.

Amen...

[Secret Agent Man]

Consider a raging mob against a person they trap in a car.

Disparity of force. Fear for your life. Gun it and get the hell out of there.
