The link above is a quick summary. This one is a fuller report.
This is the 16-page document itself.
This and indefinite detention without charges are a couple of the issues that need a better hearing, because they are disturbing, no matter who is in charge.
The problem is that during the Bush era the left railed against such practices and essentially called Bush evil while the right mostly told the left to shut up. Now the noise coming from the left has quieted a great deal (even though there are some voices still pushing the issue) while the right seems to not much care, other than to claim that President Barack Obama isn't strong enough, despite all of these efforts. I don't know what the right answer is in times such as these when our enemies have taken off their uniforms and redefined the battlefield and that drones seemed to have been so effective - even reducing the likelihood we'll launch another ill-advised full-scale war - but we should not so easily allow ourselves to get away from basic constitutional standards.
No matter how you slice it, though, these are serious issues. They need to be vetted.
