Not a surprise:
"Enrique Marquez, a friend of San Bernardino attacker Syed Farook, has been charged with multiple terrorism-related charges for his alleged role in supporting the mass shooting. According to officials, Marquez admitted to purchasing the assault rifles that Farook and his wife Tashfeen Malik used in the attack that killed 14 people this month."
It was already widely reported that he'd purchased the rifles so that Farook didn't have to worry about background checks. That's a crime right there, as it happens. Once you admit to that, in a case like this, you have to expect some heavy charges.
It sounds like he's singing like a bird, maybe in the hope of leniency. Or maybe he just likes to talk. A good interrogator builds rapport. But I assume this guy has a lawyer by now. And I assume the lawyer thinks the smart thing at this point is to cooperate, so his client doesn't end up with the federal terrorism death penalty that the Boston bomber was hit with.
It can be quite the life-changing error,
to help your best friend commit terror.
