It "prohibit or restrict the possession of firearms on any State or local government property, installation, building, base, or park." Nearly the EXACT words of what LEOUSA recognizes as valid.
OK. I was looking for something specific, but you are right.
Interesting to know. I should not be surprised given the history of property owner's rights in TXWell, it is long-established that it does. That is how we got to 30.06, and how TX/Peace Officers are specifically exempted, but not out-of-state LEOs unless their is LEO reciprocity.
Like I said, there is long-established history here. Texas CHL law was re-written several times to address it. I am sure LEOUSA will be too. Needless to say, if you check 30.05 you will see CHLS are exempt, so those gun busters signs do not apply to CHLs.
CHL gives a defense to prosecution, not an exception. Hence my statement that a CHL carrier could be arrested and prosecuted for violating a gunbuster sign, or "no firearms" scribbled on cardboard with crayon.
