Asian man with knife stabs Police man ,god what’s wrong with these people? one women lays dead hit by a car others lay injured. possibly more deaths unreported, How much more do we have to take.Barbaric seems an understatement, surely  if this is a religion of peace i can’t see it. Is this the actions of a minority or something more sinister?i worry that these actions will fracture and the innocent will suffer,how many of these cells or individuals are they at large.
