I dont see the problem personally. I really cant see why someone would be against it if it helps get convictions. If we dont have rrom for more prisoners, then do what they do in USA and keep them in tent, like tent city.
I was listening to this all day today on TalkSport and some people were moaning saying they could be wrongly accused.

Well DNA can not soley be used as evidence to convict apparently so that blows that argument out the window.
