A bold statement there BH.
I just wonder what atrocities they have prevented and if you bring the US intelligence community into play, love them or otherwise we in the UK would have been hit more times than 7/7 without them.
Who knows, that's the nature of the business innit. All secret squirell stuff and that.
The only way you can judge it is by its failings that we know of.
Four major terrorist attrocities in the last few decades. The MI5 knew of the bombers cell for up to a year before the 7/7 attack, but they completely under-assessed the threat.
What is to prevent a tragic systemic failure like that happening again?
And just how many of our Spies have been caught trying to sell our states secrets over the years?
Oh, and not to mention the Iraq and "45 minutes" that resulted in our international security WORSENING.
God knows how many failings in Northern Ireland now with these new age republicans as well as the rest of the history.
The butler report over Iraq;
'But the report came to a very British conclusion - yes, there were failures but no, no individual can be blamed.'
Yes, no individual. It's either political whitewash, and or systemic failures in the way our country deals with humint and other sources of information.
How many rendition flights? How many people have the British Secret Services helped or been complicit in kidknapping people from around the globe at will?
Too many accusations are thrown at our security services for me to be entirely confortable with their efforts/ethics at times to be honest.
