Some Federal buildings have metal detectors. Feds tend to ignore State laws, so it's up to us to know if it's legal to carry there. The Earl Cabell building in downtown Dallas comes to mind. Sure, it has Federal courts in the building, but there are areas and offices that are not part of the court. Yet, access to the entire building is controlled with metal detectors. My Federal job site has "No Weapons" signs on the floors we occupy that cite Federal law. I have no doubt that a CHL holder would be arrested if someone determined a CHL holder entered our workspace armed.

To be clear, I don't agree with this Federal policy. It is my responsibility to know where I am and that I am legal to carry there.
Hope that helps,
