If you want no help from your MP state that you're a die hard voter for them. They then know you're in the bag and your views can be ignored.

As you point out, the two groups to get are the undecided and the other lot's voters. As long as you win more accross than you alienate you're quids in.

In Yes Prime Minister the discussion on getting Trident was as you say with CCTV - false reassurance. Somehow having some massively expensive weaponry we're all safer and so defence is Sorted Out.

CCTV I think is OK. It is in public areas and although I do not feel that this is instead of a police presence it is a useful adjunct.

ID cards could be - provided the scheme is though out by bright people - be a good thing. Sadly it wasn't so it'll be a wasteful mess.

IF ID cards could replace several others this could be useful. If it could include very important encrypted medical information - this would be useful.

Terrorism / Immigration and the deaths of children will mean that the herd won't bat an eyelid until everyone is GPS tagged with a C4 charge.
