Not the crims that come to mind when talking about surveillance, encryption, terrrrrism etc. They usually eat in 5 star restaurants and get the dinner paid by the common pleb - us tax payers, who are supposed to be grateful that they protect us from whatever it is they think threatens us. (I'd argue that terrorism is a minuscule risk in comparison to truly ciminal pot holes on many British roads, but I'm getting carried away... again..)
