I’ve wondered about these “surrounded by protesters” moments where they start beating on the car / breaking glass / etc.
Pretty sure you’d be justified (again, Texas) in killing any number of them, until the mob pulled away from your vehicle. Castle doctrine is incredibly powerful.
No human can stop a 100hp car moving forward at 5mph.
Just keep driving, slowly. Windows up, doors locked, do not interact.
By moving forward slowly, you are giving street blockers a chance to simply walk out of the way.
If they want to be slowly rolled over, that’s on them.
Ditto if they jump on your hood. Keep moving forward, no matter what.
If they break a window (possibly to throw in an incendiary) or they point a gun at you, accelerate to the best speed you can make. At that point, deadly force is justifiable.
If they jump on your hood, and you have moved past the other street blockers, accelerate, then brake-check and they will fly off. Then drive around them on the ground and depart the area.
The antifa terrorists will have recorded your license plate, so when it’s safe, call 911 and report the incident, and what you did to save your life. Just like with a justifiable shooting.
