Yup, with a side order of pigshit
To be fair to Frau Hitler et al, there's nowhere left for them to go. Even though they're staring into the abyss, the only thing they can do is jump in.
What would happen if a massive attack of common sense hit Westminster and they decided to scrap the ID cards? They would be seen as (a) untrustworthy, (b) simply grubbing after votes in a last-ditch attempt to cling on to power and (c) having wasted an enormous amount of public money and achieved absolutely nothing. I daresay there would be some whining from over the Atlantic about going soft on terrorists as well.
At least by sticking to their line that ID cards will keep us all safe from harm, eradicate terrorists overnight, flush out all the illegals and drop them in weighted sacks off the White Cliffs of Dover, reverse global warming and cure cancer, they can be Seen To Be Doing Something, even if will be as effective as pissing on a forest fire.
This is what happens when people don't pay attention to the politicians they're handing power to, and instead vote Conservative because of all the illegal immigrants, or Labour because of wot Thatcher did or just sit on their lazy arses because they insist on their democratic right to do so. The bar's now so low that any bunch of second-rate shit-sorry losers can gain the power of life or death over us provided they look good on TV and can spout meaningless drivel without stumbling. And that's what we've had for the last 13 years.
 Yeah, yeah, I know, Godwin's Law. So bloody what.
