<p>Actual Law: [12551</a> thru 12601 Minors, Blowguns, Picketing, Less Lethal Weapons - Dangerous Weapons Control Laws - Bureau of Firearms - California Dept. of Justice - Office of the Attorney General](<a href=“http://ag.ca.gov/firearms/dwcl/12551.php]12551”>http://ag.ca.gov/firearms/dwcl/12551.php)
Focus on 12556</p>
<p>I think it also violates the Residential Hall Rules (see rule 18)
