Here's DiFi asking Brennan about Anwar al-Awlaqi, pointing out that he wasn't exactly a model citizen..
That he was a bad guy is largely indisputable, but it's not the point. The point is having the executive determining who the model citizens are and who belongs on the kill list, with only marginal oversight from the House and Senate Intelligence Committees to keep them honest. Cue the Machiavelli. Someone should have asked whether a president Palin would be trusted to make those lists.
Errata-- notice DiFi asked about the underwear bomber, Hasan and Shazad. Once again they ignored Abdulhakim, the Memphis jihadist who shot two Army recruiters in Little Rock and killed one. He also spent time in Yemen and swore oath to AQ, yet the US Govt allowed the State of Arkansas to try him on capital murder charges instead of federal terrorism charges. Too bad Brennan didn't have to answer that question, but he would have certainly had a complex one.
Another errata-- notice also how tight-lipped Brennan was about Awlaqi's terrorist ties. Could it be due to some connection to this dude? After all, what hadn't been reported in the press about him?
