The Washington Post reports: One perpetrator was an automobile thief before he got religion, and served time in a Belgian prison on a carjacking charge. Another was an armed robber who once shot a police officer while fleeing from a crime scene.

Others had convictions for burglary, drug-dealing, larceny and assault. Nearly to a person, all had been violent men, long before they became foot soldiers for the hyper-violent Islamic State.

Some recruits have scant knowledge of Islam but, attracted by the group’s violent ideology, they become skilled and eager accomplices in carrying out acts of extraordinary cruelty.

“Some of these guys are just looking for an opportunity to justify their violence and criminality,” said Ali Soufan, a former FBI counterterrorism official and a consultant to government agencies on terrorist threats. “Now, with ISIS, it is justified — because they can say they’re doing it for God.” ISIS is another name for the Islamic State.
