ABA Backs Federal Court Trials of Alleged 9/11 Plotters
There are at least two very good reasons to oppose these trials that don't require one to be a conservative or anywhere close to the right.
1) They are nothing more than show trials.
2) They will likely make very bad law for future criminal defendants.

Apparently these reasons aren't even enough for the ABA. At least they are showing their true colors.
