Clearly the way the problem is currently being managed presents challenges. However, that does not mean that we must completely reject the model of an independent police service and an independent intelligence service with binding legislation governing the way they operate.
I think that as parliamentarians, you could give the intelligence community clearer directives concerning the threshold for investigations, so the problem would really be addressed. With 30 years' experience as a public servant, I always see the problems that creating new institutions creates.
