I'm not in any kind of weapons or strategic area, but I've been through a fairly strict security check within the last couple of years. More stringent than my position would normally require. We've got key cards and palm scanners to get in the door. We have cameras spying on our every move. Taped telephones. Multiple firewalls. Plenty of security, one would think.
But the boss, a politician of sorts, loves to bring total strangers on tour through our work area a couple of times a week, we have the ability to record the entire network on CD's or USB drives, we don't shred our "sensitive" documents, and we have unfettered Internet access.
Typical of the government, security is a fancy facade, but like an egg, beneath the shell is a runny mess.
