Any of the objectors up above have any suggestions as to how the police and security services should gather intelligence of the activities of extremists who plan to do the rest of the population harm?

If you haven't any, then vote for those who in this day and age will cancell the funding, then you can sit back and wait for blows to land then react to them from a position of complete and utter ignorance, but whatever you do, don't blame either the police or the security forces for having done nothing to protect you.
