Show me the ‘law’, because it doesn’t exist.

‘Schools’ are not listed as ‘off limits’.
“Opinion No. 7097 January 11, 2002 A person licensed by this state to carry a concealed weapon .By its express terms, section 234d prohibits certain persons from carrying a firearm in the enumerated places but explicitly exempts from its prohibition [a] person licensed by this state or another state to carry a concealed weapon. Thus, any person licensed to carry a concealed pistol, including a private investigator, is exempt from the gun-free zone restrictions imposed by section 234d of the Penal Code and may therefore possess firearms while on the types of premises listed in that statute. “
Of which ‘schools’ are not one of the ‘prohibited’ places.
