Are there any among the other 49 states that don&#x27;t permit self-defense when being pursued by an attacker with a knife?<p>edit: The difference is that some states have a requirement that the defending party retreat.  Got it.  For my part, I imagine I&#x27;d always retreat if given the chance and if it&#x27;s reasonable (ie, I&#x27;m not going to retreat and leave my family in harm&#x27;s way, etc).  Of course, I can&#x27;t fault anyone for making a different choice; who knows how one might act in such a situation.
