«Comey also expanded the use of sting operations to catch would-be terrorists before they struck, and some of the practices were suspect. Last May, the Intercept reported that agents “busted” a mentally ill homeless man for claiming he had connections to ISIS. In a similar case, an informant also gave a homeless man $40 so he could buy the weapons — machetes, knives — he said he needed to carry out the attack.

Meanwhile, those stings didn’t stop actual terrorists. As the Intercept notes, the FBI looked at least twice at the man who eventually killed nearly 50 people and wounded another 50 at an Orlando nightclub in June 2016. The FBI, apparently, didn’t consider the man a threat during its investigations.»
