ON PLATFORM one at Bolton train station in England a mob of about 100 men punch the air in unison as a chant - "Muslim bombers, off our streets!'' - goes up. Their voices echo loudly, and as more men suddenly appear, startled passengers move aside. The protesters wave St George's Cross flags - the red and white English national emblem - and raise placards. Some wear balaclavas, others black-hooded tops. There is an air of menace.
