I dunno, I definitely feel like it's been drilled into me that in any kind of physical altercation, my duty is to escape and retreat, and that if I hurt my attacker in any way, that might be used against me in court. And even if I successfully press charges against my attacker, and they go to jail, if I hurt them in the course of their attack on me, I can probably expect to get sued.
I agree that many of the lawsuits are absurd. I also don't like the "duty" wording. Sure, you want to avoid, deescalate, flee, then fight. But codifying it as a duty seems to ignore just how messy and instantaneous those situations can be.
