A BOMB was detonated at a pop concert in the northern city of Manchester, England. The latest count of 22 dead and more than 50 injured is testimony of the cruelty perpetrated in a closed venue where people were about to leave at the end of a performance by American singer Ariana Grande. Terror has come to European cities. Granted that the current spate is garbed in Islamic extremism and blamed on the infiltration of refugees from the war-torn Middle East, but in several instances the perpetrators are homegrown as that occurred on London’s Westminster Bridge and Westminster Palace, and that in Brussels, and the Charlie Hebdo office in Paris. Whether Islamic State or al-Qaeda inspired, the perpetrators in Europe are believed to be disgruntled European Muslims.
