Whats the real reasons behind this bollocks?
The real reason behind this bollocks, in my understanding, is getting votes, which m0rt earlier on already stated. Look at it like this:
You are the current conservative MP for Frimpleton. Your Labour competitor criticises your lack of action about the security of the local primary school where a child was followed by some real pervert with a compact camera. To be seen as more vigilant than you he proposes a law that forbids cameras in the area around this school.
Now, from your position it would be political suicide to speak against that: You would be siding with the perverts. You also can't just say that it is a good idea, because he was first and you would be 'riding the bandwagon'. So, to get ahead you have to step it up so that he appears to not be stringent enough: You suggest to ban all cameras in the constituency.
The ball is now back in his field. He faces the same dilemma and needs to raise the level of action. As a result the school and approaching roads are now to be covered with blackout tunnels, so that parents can pick up their kids as they are, one by one, but through a kind of airlock. You counter this idea by stating that this opens up the possibility of getting the wrong child handed out and advocate a 'chip and pin' system with a code that the parents have to provide to obtain the correct child.
Your opponent brings up the argument that this might be error prone and to complicated to enforce and has the better idea of an automated system with several failsafes: face recognition of both parents and children, together with DNA testing and skin-embedded NFC tags on a cloud-based, nationwide platform*.
And so on . . .
Not to raise means you lose. To lower measures means to lose. The only way is up.
*At which moment the original pervert gets all his kiddie pix from the badly secured (because it was created by some ICT advisory panel that has members qualified by having A-level knowledge in PowerPoint) cloud storage without having to take them himself. But that's not the point.
