In every example from Savile to Rochdale There were years or decades of kids coming forward and being ignored by police or branded troublemakers. Officials in public and private sector suppressing stories for various reasons. And in many cases, officers themselves being involved in abuse.

You don't fix these problems with people in various positions of power, by handing them more power. The GCHQ have a long history of infiltrating trade unions and protest groups; I very much doubt their motives.
