Does the Home Office use BBC drama to get its points across?

I was an IT security consultant for many years, so was basically paid to be paranoid (a cynic might say paid to sell paranoia), and I've wondered the exact same thing for many years.

Spooks was perhaps the most obvious of these on UK TV, but I've seen the same types of things on Australian and American shows. The shows 24, Threat Matrix and E-Ring spring to mind (the last 2 of which I was a fan of) - and all are part of the new breed of post-9/11 "national security" shows that have a heavy "invasive technology is actually good" or "we have to do bad things to stop the bad guys" content that I'm inclined to think is meant to sway viewer opinion on things like Extraordinary Rendition and other "ends justify the means" activities.

Or maybe I spent too long working in security...
