If the English authorities are fair dinkum about doing something about this hostile issue with radical Islam, then they can make a stark example of Cleric Anjen Choudary and all those associated with him. Put the cleric in Jail, and BAN their venue, and remove their freedom to assembly, cut all tax payer funded support/assistance that their special interest group likely receives while they are at it. I'd also crack down on all other known Islamic groups that aren't happy with " western " ideals/values and shut them ALL down, just like Australia did recently with bikie gangs, making it illegal for them to be part of a bikie club etc.
Something needs to be done and it must be done with an IRON fist. We don't need to apologise, nor should we continually bow to this group, we have only allowed them to get away with murder...
DO SOMETHING ABOUT IT and DO IT NOW !
