Authorities say there were not just one but two Muslim men plotting a terrorist attack last week in Chicago. Both allegedly scouted targets. Both talked at length about their plans.

But by the time the FBI’s fake car bomb was parked outside the Cactus Bar & Grill in Chicago on Friday night, only Adel Daoud, 18, was there to push the button on what he thought was a detonator. Only Daoud was under arrest.
