Killing several birds with one stone*
I feel there is a consensus that the Chav/Scumbag/Lowlife dumbshit issue is one that will take many many years to deal with - all that education, job creation, training etc will take years.
I firmly believe I have an answer.
Anyone on the street wearing more than 3 items of sports-branded clothing (trainers excepted) should be rounded up into a van and given a basic intelligence/general knowledge test - y'know, nothing too taxing but the kind of thing that the late sainted Jade Goody would have failed miserably. As and when they fail, DNA test them and give them a barcode tattoo, then release them into the wild.
Now the clever bit.
When a worthwhile, tax paying CONTRIBUTOR to society needs an organ (you can see where this is going) then we have a huge database and bank of compatible organs, all being kept nice and warm by the aforementioned scumbags. So! We find them, cull them (humanely, of course) harvest the organs and Bob's your uncle, a repaired useful member of society, back in the land of the healthy and one less oxygen-thieving waste of DNA roaming the streets.
This would drastically reduce the transplant waiting lists, hell it may even get us loads of foreign cash as we could well have a surplus of organs we could export!
There is a serendipitous side effect of this. Once the word getrs around that this is likely to be their fate, the oxygen thieves might just leave, hopefully to our nearest neighbour - France. So we could end up pissing off the French - as I see it, a plan with no drawbacks.

Vote for me!
