The Islamic State issued this call in September 2014:

So O muwahhid, do not let this battle pass you by wherever you may be. You must strike the soldiers, patrons, and troops of the tawaghit. Strike their police , security, and intelligence members, as well as their treacherous agents. Destroy their beds. Embitter their lives for them and busy them with themselves. If you can kill a disbelieving American or European — especially the spiteful and filthy French — or an Australian, or a Canadian, or any other disbeliever from the disbelievers waging war, including the citizens of the countries that entered into a coalition against the Islamic State, then rely upon Allah, and kill him in any manner or way however it may be….If you are not able to find an IED or a bullet, then single out the disbelieving American, Frenchman, or any of their allies. Smash his head with a rock, or slaughter him with a knife , or run him over with your car, or throw him down from a high place, or choke him, or poison him….

“18-year-old suspect in Fountain Hills deputy-involved shooting now accused of terrorism,” azfamily.com, January 16, 2019:

FOUNTAIN HILLS, AZ (3TV/CBS5) — An 18-year-old suspect accused in a deputy-involved shooting in Fountain Hills now faces charges of terrorism.

The Maricopa County Attorney’s Office says Ismail Hamed, who was shot and injured in last week’s shooting, is now charged with two felony counts of terrorism.

County court records state that Hamed allegedly provided “advice, assistance, direction or management to the Islamic State of Iraq” and ISIS on or about Jan. 7.

It’s still unclear whether what happened at the Fountain Hills substation was connected to the terrorism charges, but former assistant U.S. attorney Andrew Pacheco says it could be.

“It’s too early to know what all of the facts are, but this is absolutely consistent with somebody answering a call for Jihad on a lone wolf basis,” he said.

Pacheco has no connection to Hamed’s case, but he says Arizona’s anti-terrorism statutes are quite robust. He says if Hamed had any online contact with ISIS, for example, that might have come to light during the investigation following the rock-throwing incident.

“They likely conducted an interview, and let’s face it – people who engage in terrorist activities are quite proud of what they’ve done and so they often like to talk about it,” he said.

Hamed was previously facing two counts of aggravated assault on a police officer and one count of aggravated assault with a deadly weapon in connection to the shooting.

MCSO says on Monday, Jan. 7, Hamed threw rocks at a sergeant outside the sheriff’s substation. MCSO says Hamed then brandished a knife and advanced toward the sergeant, despite his repeated commands for Hamed to drop the weapon….
