We had a security manager at work who went on secret missions in iraq in his spare time,had an arsenal of weaponry in his house,hunted rabbits with uzis,hunted deer in a helicopter with kalashnikovs-the list of insane tales he would tell you were legendary,and he was soo convincing when he told you this stuff.
He left,his replacement arrives and guess what? he is ex-sas,used to drive "all the secrets down the motorway to tony blair every monday??" and if they were approached by a car that "looked dodgy" they were authorised to open the van doors and fire a rocket launcher at it! and although he will take the secret to the grave,he knows 17 ways to kill a man with a matchbox.
are all security guards army/gun fantasists? seems strange that the two most insane people I have ever met share the same profession.
