Not these days. You would not believe how tight the Federal Marshals are. They make the air police look like kindergarden teachers. Yeah, it does amke me nervous. I've got some titanium and reinforced nylon 'tools' but I don't want to risk it. Losing them to confiscation is the least of. If you go to such lengths to 'infiltrate' a federal facility, you have made out a prima facie case of 'intent' for them.
