It seems to me that the bill was designed to prevent those who will not obey the “no guns” signs from bringing guns into “sensitive” places by installing thorough screening methods for ALL who enter.
So we continue to disarm the honest subject while those with bad intent walk right in with guns to do their worst with no fear of a good guy being armed and able to prevent or halt their bad intentions.
Or am I confused?
You are correct. The bill requires governments that wish to ban weapons in their facilities to actually do so, instead of simply putting up signs that only prevent the law abiding from carrying weapons in their facilities.
