[spoilers] Sir Harry Pearce 2.0

[Silktie]

Well, I think it's called "dramatic license". The same can be asked about Harry being the only one that knew where the uranium was in 8.1. In real life that would never, ever be the case, precisely to prevent that one man can be blackmailed to deliver it into the wrong hands. Otherwise, no President, PM, Intelligence Officer or senior military officer's loved ones would ever be safe. In real life it would need access codes from two or more people, or something like that, to get your hands on such sensitive secrets.

This is one instance where it'd be nice if Spooks were closer to reality, because then Harry can be allowed to love his kids and Ruth without this constant fear that they could be used against him in this way.
