You mean anti-weapon rules don't work?

Huffington, as usual, loudly announces a shooting at Delaware State University.  Of course, any shooting is unfortunate, but it is also clear how liberal and anti-gun HuffPost is when you read that the shooting resulted in non-life threatening injuries. When one is trying to score points all incidents deserve national attention.

But what do the rules at DSU say about having weapons in residence halls?

Weapons
Because of the threat of violence in our society, we are very concerned about weapons in our residence halls.  Therefore, we prohibit the possession of weapons or those items that a casual observer might perceive to be a weapon (e.g., toy guns, stun guns etc.).  Persons found to be in possession of such items or weapons may be charged with a violation of the Code of Student Conduct.  For further information on this policy, please read the student handbook.

What? Prohibiting weapons on campus didn't prevent this shooting?  You mean someone intent on committing a crime with a firearm was not deterred by their prohibition on campus?

Shocking!
