Even if they escape they'll still be on the most wanted list now. Though they have been in the federal database before, but they'd never been accused of trying to assassinate the president before, and the Sam and Dean the FBI were after were thought to be dead 9 seasons ago (aside from a brief Leviathan thing in Season 7) Unless Castiel erases their memories, we know he can do that.

Yeah, Crowley could teleport them out and Castiel could erase the memories of everyone involved.
