With the parity of force concept, I do wonder if you’re supposed to let some guy break your facial bones or whatever before you’re allowed to use a gun.

One of the earliest uses of deadly force by a CHL holder after the concealed carry law came in in Texas (‘95?) was a road rage incident..

A big Polynesian guy in stalled traffic got out of his car and started punching a guy in a pickup through the open driver’s side window. Got himself shot stone dead for his trouble.

IIRC it was judged to be a justified shoot, pickup driver was not charged.
