They ALREADY have that permission.
the context in which you use the word is giving them something they do not already have, the guns.

It's your understanding of California concealed weapons laws that is wrong. For almost all California citizens it is illegal to carry a concealed weapon in public, let alone college campus, if you're not law enforcement. However, they will make exceptions for public safety concerns. Thus, Califonia in general, does not have that permission, therefore making what I previously said about, valid.
LIMITS ON CONCEALED HANDGUN PERMITS
May police limit carrying concealed handguns? Yes
California - State law allows police chiefs and state sheriffs to prohibit people from carrying concealed weapons (CCW) in public. Police chiefs and state sheriffs ?may issue" permits that allow people to carry concealed weapons if police believe it is in the interest of public safety. Anyone so approved by local law enforcement must undergo safety training in the legal and safe use of the weapon and there are limits in where they may carry such weapons.
