Flee, do not bother with the cops.
Or the caps.
I’ve watched a lot of road rage videos on youtube. Sometimes fleeing is not the option. That’s why I carry in my car and also learned what to do with that weapon if someone actually forces me to stop. There’s a particular stance you have to use with your finger in a particular place to keep from being accused of “brandishing” the weapon.
Some of my favorite videos of the ones where the thug forces someone to stop, gets out of his car and walks to the vehicle yelling ready to pound on someone, and then quietly walks back to his car and drives off because the driver of the other car was armed.
The reason for carrying is not so you can shoot somebody when they come at you. Rather, it is to let them know how high the stakes are if they do. Anyone not on serious drugs is going to back off.
