Okay, repeal SYG.
You got a 20 something woman jogging in the park. A man tackles her, and begins to tear of her clothing. She gets to the revolver she carries in a belly-band and empties the cylinder into his stomach. Five rounds. Without SYG she is in legal limbo. The prosecutor can file charges. Under the old Duty-to-Retreat standard the Prosecutor can argue there is some super secret way for her to get away from her attacker. She now faces criminal charges and a civil suit.
Under SYG, the Judge can dismiss the case pre-trial on the basis of Self-Defense and the attacker's next of kin cannot sue her for deciding that killing the bastard is preferable to rape. Heck, under SYG she may not pay a single dime in lawyer expenses or court fees.
