I'm with Carl on this. Obviously the idea that you can be randomly murdered in a cafe is a ridiculous exaggeration but the idea that our government actually believes there are instances when it would be "Constitutionally permissible" to execute a US citizen, on US soil, without due process of law, is horrifying. And, on the off chance there is some vagary to this and Holder can actually envision a scenario where he can pass legal muster and kill someone, I hope Congress takes immediate action and passes a law stating that the President cannot do that.
Also, the Bush example fails on several levels. There is a tremendous difference between taking a decision to shoot down a hijacked airliner that you know is being piloted by people intent to crash that plane into a building with the intent of murdering civilians and specifically targeting a US citizen. One is a tough decision in a bad situation where you take the decision to kill people who are, for all intent and purpose, are already dead. The other is an affirmative decision to roll back a 1,000 years of legal precedent, dating back to the Magna Carta, to grant the executive the power to be sole arbiter of life and death. The idea is absolutely appalling, but not nearly so as the lengths people (not you, specifically) will go to justify it. Personally, I'm glad that Rand Paul tried to block John Brennan's confirmation and only wish he could have been successful. I think the man is scary and his views on issues like this are something to really worry about.
Carl - I laughed at the "not to big to bail" comment. Nice! I think the problem is that the rest of us are too small to bail.
