I was a locksmith for a couple of years. Nothing unique or interesting about that in itself, but I was a locksmith in Washington, DC, and the shop had a ton of federal and federal contractor clients.
I personally keyed about 30% of the doors in the then-new Homeland Security building, I did a ton of work around the Patent & Trade Office, I rekeyed an entire building for Raytheon, I opened and worked on safes at the NSA, Navy Intelligence, and many other extremely high-security agencies I don’t remember the names of.
However the one job that sticks out is the time I was still in training and we were called out to a stately private residence in the suburbs to open a large house safe. The owner’s husband had passed away and she did not have the combination to his personal, private safe. She didn’t know what was in it, and mentioned she believed it to contain hunting rifles, cash, and old stock certificates or something like that (I assume that’s what he told her was in it).
Anyways, it took us about an hour to drill and scope it, but once we got it open, my boss/trainer only opened the door a crack. He went to let the widow know we had finished, and as soon as he left the room I opened the safe door and looked inside. It turned out to be packed with porn and bondage gear. I closed the door (leaving it open a little) and walked out of the room, quickly had her sign the paperwork and we left before she had looked inside the safe. As we were driving away, I told my boss/trainer what I had seen and he said, “That’s why you don’t look!”
