When you're carrying, you have to maintain a higher standard. Flipping the bird at another drive under ANY circumstances while you're armed is going to get you into serious trouble.
A jury is going to believe the attorney who tells them that you flipped a guy off just so you could provoke him into attacking you and give you "cause" to shoot him.
When you're carrying in public, you HAVE to let the other guy make ALL the stupid moves. You don't have the luxury of making ANY.
Even though we have no duty to retreat in Oklahoma and our car is treated just as if we are in our home I agree with this. Anything that may look like you were provoking is considered a no no here.
