I believe some of it, but I remain unconvinced we are getting value for our money and skeptical about their self proclaimed and totally unverifiable successes. The secret service is exactly that but what I would expect from them is behind the scenes advice to the DfT so that proactive security measures can be taken to neautralise predicted threats. And I've not witnessed that over the past few years. And with proper advice, I would have expected the DfT to have been able to relax certain measures of the years - but that has not happened either.
Yes, I want to live in a safe world, but I want to live as well. I'll not cower in a corner just because someone says there are nasty people out there. I'm convinced we can do better.
