No retreat law proposed in PA
A no retreat law is being proposed in PA, according to this article. If the reporter has it right, it sounds a bit strange... only applicable to CCW permit holders.
On the other hand, it may be no stranger than the existing law. I was about to post on it yesterday when my browser crashed and I lost the link--as I remember it, the existing PA law covers self-defense in two sections, one relating to defense of self or others, the other to defense of property, and there is no retreat provision in the defense of property section, but none in the defense of self or others one!
