“Police fired a 50,000-volt Taser into the head of a 45-year-old company director who later proved to be unarmed and innocent. Daniel Sylvester, the owner of an east London security firm employing 65 staff to guard council offices, pubs and nightclubs, was driving home on October 20 when he was stopped by armed police because of ‘firearms related intelligence’.”
