I wasn't sure where to post this but this seemed like a good spot.
A question came up on a local forum about constitutional carry and federal law "gun free" zones. The specific example given was near schools. Per federal law you are within the federal law if you are legally able to carry a firearm concealed per your states statute.
This person stated that you would be in violation of the federal law if you didn't have a permit to carry and were carrying under the state constitutional carry statute instead. I don't believe this is correct but I don't have enough background on federal law to prove it.
I have a state permit so I'm not worried about it. I would like to see accurate information provided though. If someone can help me out I would appreciate it.
