Officer Jesse Hartnett was slowly patrolling his usual West Philadelphia beat just before midnight when a man appeared out of the darkness, firing a hail of bullets at close range as he charged toward the policeman's car.
Hours later, police say, Edward Archer confessed to shooting the officer and told investigators he was following Allah, and had pledged his allegiance to the Islamic State group. Archer said he believed the police department defends laws that are contrary to Islam, police said.
