I'm not surprised to hear this. With the way this government lets all and sundry into this country without checks, no wonder extremists are able to come and preach what they do. Correct me if I'm wrong, but I've read somewhere that Treason is the only offence that still carries the death penalty. British subjects going overseas to kill British service personnel in my opinion are committing treason. How can they live here with all the benefits and kill the very people who are charged with safegaurding their rights?
