How come the safety and well-being of her people doesn't concern the Queen? Abu Hamza was a threat for Britain, something everyone could see, and that includes non-British people who wondered whether Brits have completely lost their marbles for allowing someone to openly preach hatred for their country from their streets and squares. I mean, if a person chose to live in Armenia and then called it a "toilet" and called to fight against it, goodbye would have been the nicest possible thing he could hear.
The Queen obviously shared the concern, and asked her ministers how come a man who had clearly broken many laws was still at large. She's supposed to be the protector of the country's laws after all.
