I believe, under the new law, the schools can prohibit weapons within the controlled access areas of the buildings if they meet the requirements of having an SRO onsite AND controlled access (secured doors, etc.) The law does use the word 'and' regarding the two.
However, I do not think this applies to the parking lots. Access to the parking lots is not controlled in any way at most schools, so they would not fulfill the second part of the law unless they fenced the entire property and had the entrances gated with controlled access to those gates.
Wright - how do you read it on parking lots? The issue I have with the entire thing is the same issue I had with employers banning guns in cars - if you cant have your gun in your car when you pick up your kids, you pretty much cant carry the gun at all 5 days a week. If they let this stand, the gun control crowd wins by default 5 days a week in most cases.
