The Blackwater mercenaries who massacred 17 Iraqi civilians have been let off by a US judge because they gave evidence under duress – the threat of losing their jobs.
Yet evidence given by Khalid Sheikh Mohammed during hundreds of torture sessions, including over a hundred sessions of waterboarding, is admissible in the US, torture apparently not being duress like the threat of losing your job.
The US is at the same time going through more angst about the underpants bomber. Get this into your heads; people want to kill you because as a nation you behave in a murderous and arrogant way. That does not justify a terrorist in killing innocent civilians; but killing innocent civilians did not seem to bother the Blackwater boys, or the US armed forces who kill innocent civilians every single day.
