Summary execution of Anwar al-Awlaki.
Even if I could bend thinking of finding that acceptable. Eric Holder's analysis of the law and finding that the president has the power to assassinate any American citizen without trial.
Holder justifies this by separating the concept of due process from judicial process. Due process is a decision by the president after careful personal consideration. No one is really entitled to judicial process to overturn the president's decision.
Eric Holder: Yes, We Can Kill American Citizens Without Trial
The most important point to note for this entire debate is how perverse and warped it is that we’re even having this “debate” at all. It should be self-negating — self-marginalizing — to assert that the President, acting with no checks or transparency, can order American citizens executed far from any battlefield and without any opportunity even to know about, let alone rebut, the accusations. That this policy is being implemented and defended by the very same political party that spent the last decade so vocally and opportunistically objecting to far less extreme powers makes it all the more repellent. That fact also makes it all the more dangerous, because — as one can see — the fact that it is a Democratic President doing it, and Democratic Party officials justifying it, means that it’s much easier to normalize: very few of the Party’s followers, especially in an election year, are willing to make much of a fuss about it at all.
And thus will presidential assassination powers be entrenched as bipartisan consensus for at least a generation. That will undoubtedly be one of the most significant aspects of the Obama legacy. Let no Democrat who is now supportive or even silent be heard to object when the next Republican President exercises this power in ways that they dislike.
