Following an incident in which a man attacked New York City police officers with a hatchet, jihadists praised the attack and questioned if the perpetrator, Zale Thompson, was motivated by recent jihadist propaganda. Of such propaganda, jihadists seemed particularly focused on a speech by Islamic State (IS) spokesman Abu Muhammad al-'Adnani and a jihadi essay urging lone wolves in the U.S. to wage an "aggressive and sustained" campaign on targets that include policemen.
