What Privacy? UK DNA Database Could Grow Fast

An unnamed and unsampled reader writes: "According to the BBC The UK home secretary is expanding the police DNA database to include innocent people. And, of course, these can be taken without your consent if the police have 'reasonable' grounds. The police state (RIP bill, etc.) emerging in the UK is looking less and less 'reasonable' every day." The article cites Home Secretary Jack Straw as making a comparison that may strike him as more attractive than it does me, namely likening DNA testing to widespread video surveillance. According to Straw, the "introduction of closed circuit television in streets and shopping centres had been seen at the time as an attack on civil liberties but [is] now welcomed by the public." Anyone from that side of the water feel that way?
