I don't know, i think he's the exact type of employee you want. He took pictures of paper clips in drawers, love letters from Boris and pictures of staff names and cars then sent them to Vlad and his FSB stooges. What's he going to do with that they he can't already find out with a pair of binoculars and a flick through a stationary catalogue? Also, they make the sting operation sound like some 007 type shite, when in actual fact it resembles more like a sting to find out which one of your mates stole your last wine gum. They could have used David Smith to feed the FSB a bunch of cack that would take months to decipher and use their valuable resources and even detect genuine Russian agents.
But no... Lets make a headline out of some night watchman, albeit a bit of a dick, in his little gatehouse and ignore the bigger picture.
