I thought it made perfect sense, Spice. The UK/US intelligence, frustrated at knowing certain people were planning terrorist activities but unable to prove so, had concocted a way to manipulate CCTV to provide evidence. And woe betide anyone who got in the way.
I was in the Regimental Intelligence Section on my third tour of Ulster and i was privy to Confidential/Top Secret files. Of course i read them and i couldn't believe the stuff we KNEW was taking place but couldn't prove it. I'm sure had we had CCTV cameras back in the day, and the technology to manipulate it, we would have done so.
