By Jeff Edwards SCOTLAND Yard has tried to prosecute hate preachers 20 times in the past two years but only succeeded once, Britain’s top policeman revealed yesterday. But on the same day controversial Muslim cleric Sheikh Omar Bakri said the Government and public share some of the blame for the July 7 terror attacks. Met chief Sir Ian Blair went on to criticise inadequate laws – and said it showed why tougher ones were needed, such as a new offence of praising terror atrocities. He said: “We have got to find effective new legal means of dealing with people glorifying terrorism and encouraging youngsters to carry out the sort of shocking atrocities we have just witnessed. We have got to find new ways to prevent and investigate terrorism.” Sir Ian added: “On 20 occasions in the last couple of years we have put different pieces of evidence to the CPS – sometimes about the same people. Only once have we been able to cross the boundary of incitement to murder.” He went on: “You cannot commit a criminal offence that does not exist. That is why we need a new offence. ‘Glorifying terrorism’ would do very well.” And the Met chief said it was vital police liaised closely with Britain’s Islamic leaders to “identify and stop vulnerable young men and women being drawn into terrorism”. Mr Bakri, a Syrian-born father of seven, said: “I blame the British Government, the British public and the Muslim community in the UK because they failed to make the extra effort to put an end to the cycle of bloodshed which started before 9/11 and on July 7 was devastating for everybody.” He condemned the July 7 attacks but said it was not enough to blame the four suicide bombers for what had happened. Meanwhile a British fanatical Islamic leader yesterday described those killed in the Tube and bus bombings as “specific targets against a specific nation”. Anjem Choudary, leader of the disbanded Al Muhajiroun, refused to condemn the 7/7 atrocities. Instead he blamed the British people for re-electing Tony Blair and his “lackeys” in mainstream Muslim groups. The parents of a New Zealand woman killed in the blasts paid tribute to her at a London service yesterday. Kathryn Gilkison – who flew to the capital after daughter Shelley Mather, 26, died in the King’s Cross Tube blast – described her as a “beautiful and vibrant young woman”. And a vicar whose daughter was also killed was given free rides by two taxi drivers as she travelled to London to mourn. Rev Julie Nicholson – whose daughter Jenny, 24, died at Edgware Road – had been heading to St Paul’s Cathedral with Jenny’s boyfriend James, 26, to observe the two-minute silence. CIRCLE Line Tube services should be running normally within two weeks, London Underground chiefs said yesterday. Full services should run on the Metropolitan line and Hammersmith and City lines from Monday.
