Earlier today I came across a story of a man who was locked in solitary confinement for 22 months after being picked up for DUI - he was never charged, never tried, never even brought before a judge.  The man was just left to rot - literally, as when one of his teeth rotted badly enough, he had to extract it, himself.  This was not, however, a deliberate act of injustice on the part of government - the man was simply forgotten about.  That is what is really more of a threat than whether or not Holder will zap someone with a drone strike.  The government has grown so large that in practical, day to day terms, no one is in charge and it just rolls along - with people only intervening when something screws up so badly that it can't be hidden from the public.  I don't think that Obama will ever actually order a drone strike on an American inside the United States, but I do believe it could happen because someone, some where in the bureaucracy thinks it should...and as there's no way Obama can even know one in ten thousand things which go on each day in government, it'll just happen.  Afterwards, of course, post-facto justifications will be issued...which is why I think that Holder initially gave his non-answer to the question...this better answer does, of course, leave some gray areas there...and if we're one day looking on TV at the smoking rubble of an American's home, you can bet your last dollar that it'll be said that the dead were engaging in combat against the United States.
Of course, while we have this gigantic, no-one-in-charge government, people who want to steal are, naturally, robbing us blind.  Via grants, loans, contracts and kickbacks, there is a massive amount of theft going on...this is the standard outcome of an organization grown to large to be managed:  the boss can't keep tabs, but those who want to steal will make certain that their theivery goes on.
Left or right; hawk or dove; conservative, libertarian or liberal, this has to be recognized as the fundamental problem:  government is too large.  Even if you want it to do good things, it is so large that for the most part only bad things will hapen.
