The first paragraph:
This white paper sets forth a legal framework for the...use [of] lethal force in a foreign country outside the area of active hostilities against an American citizen who is a senior operational leader of al-Qa'ida
Then you apply the logic which hinges on it being a foreign country and parallel that to a condition in our own country and it gets ugly. After reading this whole memo, I actually see very little about geography or why this wouldn't be legal in the US. The bottom of page 4 and top of 5 seem to actually justify executions within our borders.
The consequences of going to war, is that the executive (President, acting as Command in Chief of the armed forces) is authorized to kill the enemy without judicial review.
> lethal force [..] against an American citizen
Wherein lies the difference?
Reading comprehension, mostly.
