Does anyone remember a casino in Lake Tahoe that blew up in 1980? One of my co-workers was contacted by the FBI - turns out his MOS years bevore had been explosives of the type/configuration as had been used on the casino. Apparently, very few people had that type of expertise.
Never heard about that one.
I was actually a grown adult before I learned that the first of the post office shootings that led to the coining of the phrase "going postal" occurred in the same post office I mailed my selective service registration from 15 years later.
