This was a little confusing until reading further down for me. I read it "proper signage" thinking 30.06 or 30.07 but the point you make is about any sign at all. I would word it something likeAnother misconception is that proper signage to prohibit open, concealed, or any form of lawful carry serves to prohibit handguns on the premises.
Another misconception is that any sign prohibiting open, concealed, or any lawful carry serves to ban guns on the premises in reality.
This is factually inaccurate. There was an armed student on UCC but he was in a nearby building and chose not to go looking for the shooter. TTAG has a good write up on it. http://www.thetruthaboutguns.com/2015/1 ... e-killing/Maybe Umqua College, site of a mass shooting in October, if you squint a little. College policy banned weapons but Oregon State law made the policy unenforceable. The policy and the anti-guns signs were there, though. Good law abiding gun carriers respected the intent. Nobody was armed except the murderer
