I'm a federal Pentagon employee in temporarygovernment leased spaces at Crystal City, Arlington VA, atGateway North, the closest building to the Pentagon (five minute walk). Will be moving back into the Pentagon next year once our Pentagonspaces are renovated.
My understanding is that the entire Pentagon reserve which includes the surrounding parking lots (north/south)are on the reserve which mean they are "Federal". There are some parking lot next to I395 and Navy/Army Drive which are gray areas (Arlington vs Pentagon Jurisdiction at times). If they are patrolled by the Pentagon Police, it issafe to assume they are part of the Pentagon reserve and "Federal". I would tell you to...that civliianguns are " Federally prohibited" on those parkinglots inthe Pentagonreserves "in your car or on your person" and In the Pentagon. The Pentagon Police (Federal) response isvery quick to anything or reported events in and around the Pentagon reserve and have seen them shutdown a whole parking lot searching. I don't think they are too versed in Virginia Law.
The government "lease" space/floor that I work in, guns are " Federally prohibited" but I don't know about the rest of the entire building. If we have a problem or alarm, thePentagon Police will respond to our leased area/floor in our building InCrystal City. This whole area is a OC and CC minefield. Since I metro from Huntington to Crystal City to work, I justleave my weapon in my car at the Huntigtonmetro carparking.
If you are CCing on the metro,"I suggest"do not exit the metro at thePentagon or Arlington Cemetery with a concealed or open weapon, because those metros exit on tothe federal reserve. Infact in Virginia exit the metro before any metro train goes into Washington DC or Maryland Jurisdiction....So Don't fall alseep and miss your stop
I have CCed only on the Metro in Virginia and seen open weapons and poorly concealed (printing) weapon on the metro in the Virginia jurisdiction. Again don't fall asleep.
Hope this helps...Do at your own risk.
