@jbouie This is a good article! Great point about equating Foster and Rittenhouse.
My main quibble is the way Balko is describing the driver immunity laws.
If you're driving and your car is surrounded and attacked, I think it's pretty reasonable that you should be able to try to get away, and aren't really responsible for the safety of an attacker that is in front of your car. (See Alexian Lien, for example.) That's clearly the point of e.g. the Oklahoma law, which is what I'm assuming Balko's referring to.
(I don't know if we have any reason to think Perry was in this kind of danger, though, and "I didn’t want to give him a chance to aim at me." seems to settle that case!)
