A few months after 9/11, I was transferred to a new program in a different building on the air base. This building was located squarely in what was known as "downtown," a very busy, concentrated area known for its lack of parking. It was about a mile from my previous building.
After meeting my new boss and getting read in, I asked if it would be OK to move into my new digs over the weekend to avoid parking issues. No problem he assured me as the cipher lock combination I was given me would allow me to enter the facility 24/7. He even offered to detail a young 2Lt to help, but I declined.
The following Saturday as I was carrying boxes into my new program office, someone yelled, "Put the boxes down and put your hands against the wall." As I was putting down the boxes, out of the corner of my eye I saw two young security police officers with pistols drawn. After they frisked me, they started yelling questions....who I was, what I was doing, what was in the boxes, etc.
Within a minute the security forces duty NCO came in and immediately ordered the two airmen to holster their weapons. Before I could say anything, one of the airmen told him they had "caught me" going into a secure facility with suspicious packages.
Long story story short, things got sorted out quickly with the adult supervision of the NCO. He sent them on their way, then apologized for the overzealous of his young officers. I wanted to file an IG complaint, but my new 0-6 boss asked me to let it drop due to everyone still having 9/11 nerves.
