Perhaps, but America is still operating under the context of two massive skyscrapers plummeting to the ground from an attack carried out with almost military precision. It's not as if Bush Jr. just woke up one day and decided that it was time to whip up some secret prisons. So if "context" is a defense then there's at least a little of it to spread around here as well.

So that excuses any human rights abuses?

Feel free to point me to where I said or implied that.
