I know of cases in telecoms where a couple of BT workers got 10+ years for conspiracy - provided information to a gangland hitman to murderer someone's parents.
And anecdotally in BT you would hope if you got caught for naughty shit you would rather the Local Police, The Met or The Service caught you instead of the internal security.
