if you witness a murder or other illegal acts, your contract binding you to silence loses all weight.
as for the drone strike, it wasnt a happy coincidence, it was a targeted assassination of an individual, done in the full knowledge of his citizenship, and outside of any active combat.
Make no mistake: the guy WAS a terrorist. i'll even say he absolutely deserved to die.
But that doesnt give you, the President, or anyone else the power to simply bypass the Constitution, Due Process, and the basic rights granted to all American Citizens, including those we'd very much like to see dead. The very idea should turn the stomach of every American citizen.
The GOP is so hopped up fighting mad and ready to impeach Obama?
THIS IS WHAT THEY SHOULD USE.
But they don't.
And they won't.
Because they actually support the doctrine.
As I've said before: Most of the complaints of the GOP and Fox are manufactured bullshit meant for mass consumption of their voting base.
The real issues, the real problems that should be held against the President, like this one, they don't actually care about and/or actively support.
