We also now know that MI5 were tasked with investigating at least one child-abuse suspect because the police couldn't be trusted to do it. I suspect we're just scratching the surface here.
The police have lost credibility over recent years because they have lost their independence and have just become an arm of government, used by successive governments to keep the public in line - possibly the first and most obvious example of this was their policing of the miners strike, back in Thatcher's day.
And now the Courts, which are supposed to act as a check on the police, have become just another arm of government too.
And the press, which has always had a very important role in bringing injustices to public notice, is severely restricted, so that longstop has effectively gone.
And the IPCC, which is supposed to investigate police actions, is seriously under-resourced and its terms of reference actually prevent it from doing what it's supposed to do, so basically we have all of these systems in place but none of them are actually allowed to work.
Funny, I was having a conversation about freedom with a Chinese friend who has just come to this country only last week. To her, it was great to be able to join Facebook and to be able to have freedom of speech - but I pointed out that, in this country, we have the freedom to disagree with government and the freedom to demonstrate peacefully, but for all the good it does, those freedoms may as well not exist because they have no effect on government.. For example, about 1 million people demonstrated against the Iraq war but our politicions took no notice whatever - was Robin Cook really the only labour politician who could tell right from wrong?
The irony here of course is that M15 is a branch of government too, it's just that they are not part of the community, have no local affiliations and loyalties and so can be trusted more than the police.
