That law about driving by a school with a gun in the car was defeated here in Texas.That is no longer a crime since CC and the new defination of travel.
It's no longer a state crime, although I'm not so sure about that effect in the new law, but it's still a *federal* crime. The Gun Free School Zones act was declared unconstitutional by the Supreme Court, in Lopez (schools are not commerce so Congress has no power to regulate them). But then Congress sprinkled on a few more Whereases and some "interstate commerce pixie dust and passed the thing again. The second version had not yet been tested at the Supreme Court level, AFAIK.
