The US has been killing Islamic State fighters with airstrikes and drones, but now 300 Special Forces are on the ground in Iraq. They're conducting so-called "targeted raids," and taking prisoners. But they're not the only ones. Today, Kurdish Peshmerga reportedly captured a US citizen, Mohammed Jamal Amin from Virginia — who is said to have entered Syria from Turkey and then made his way to Iraq — complicating the issue of what to do with ISIS detainees. Questions about "enhanced interrogation" and Guantánamo Bay are already being raised in the presidential campaign.
