One of the scary proposals is to make it illegal to have a gun “near a school.” I assume that would make it illegal for a homeowner who lives near a school to own a gun. That would affect millions of gunowners, because anyone who lives in a city or a suburb lives “near a school.”
Also, anyone walking or driving past a school, with a gun on their person, would be in violation of that law. That law would end up being a nightmare to enforce.
