Federal agents are investigating last week’s shooting of a Philadelphia police officer as a terrorist attack, reports the Philadelphia Inquirer. FBI director James Comey’s comments on the case marked the first time investigators have characterized last Thursday’s shooting of officer Jesse Hartnett by a man pledging allegiance to the Islamic State (ISIS) as a potential act of terror. When he was arrested, shooter Edward Archer invoked ISIS and said he shot the officer “in the name of Islam.” Investigators have been working to determine whether Archer, 30, had contact with or help from anyone with ties to terrorist groups.
No conclusive connections had been found in the week since the investigation began, law enforcement sources said. Still, federal agents continue to review Archer’s online activity, recent communications, and trips he took to Saudi Arabia in 2011 and Egypt in 2012. Authorities believe they have identified the three men mentioned in an anonymous tip to officers Saturday that warned “the threat to police is not over.” A woman approached an officer on the street and said Archer regularly associated with the men, whose religious beliefs she described as radical. Comey said ISIS has recently focused on “crowdsourcing” terrorism and trying to motivate “troubled souls” to commit violence on their own without direct contact with the group.
