Plots about to unfold, involving foreign national based in foreign lands, little more than discussions about possible attack scenarios are now being busted by the US Authorities. Of course it is a good idea to prevent terrorism going ahead, but to get a conviction, there used to have to be a crime. Not just talking about it.
The actions of this US Adminstration include kidnapping sweeps of their enemy based on "intelligence" (perhaps the admissions of prisoners under some form of extreme torment), leading officials who do not question torture as a strategy and who also engage in imprisonment without trial of hundreds of foreign nationals. Either these acts are wrong, or international law is wrong.
