The courts have now determined parking lots are off limits for gun! (updated 2023)
Concealed Carry Not Allowed in Federal Facilities
The federal government prohibits firearms in federal facilities (which includes post offices, IRS offices, etc.).
Violating this prohibition may result in federal charges, and imprisonment up to a year.
However, this prohibition does not extend to post office parking lots. In July of 2013, U.S. District Court Judge Richard Matsch ruled that the previously enforced USPS regulation that extended a ban on firearms to USPS parking lots was not constitutional.
The term Federal Facility means a building or part thereof owned or leased by the Federal Government, where Federal employees are regularly present for the purpose of performing their official duties.
This would include federal courthouses, IRS offices, Post Offices, Ranger Stations, and other buildings in Federal Parks, etc.
Concealed Carry
This is great news for most of us that have been trying to comply with a law that was very unreasonable. Remember that Concealed Carry is NOT PERMITTED in the Post Office and other Federal Facilities.
Remember that as a Concealed Carry Permit holder it is your obligation and responsibility to keep up to date on the Concealed Carry laws for your state, and the Concealed Carry laws of any state you might travel in with your firearm.
