My suggestion would be to contact your States Office of Attorney General, or your States Legislative Representative. There are two reasons for this, one is you get it from the horses mouth, so to speak. Secondly, many states are constantly modifying their laws, and those modifications don't always show up on the internet or sites that are supposed to keep track.
Although I no longer live in Texas, as a Concealed Carry Instructor still certified there, I get updates every Sept. after a legislative session. These updates are important as they may include additional areas that are "Off-Limits", or information on formerly off-limits places that now allow carry.
One additional location you may find what you are looking for is at a Police Supply. I am talking about non-city or county owned businesses that sell supplies to Police, and Security personnel. Penal Codes for your state, in it's most current form should be available for about $40 - $50 a copy.
