Why the automatic presumption of guilt here, and what's the problem with these detainees getting a fair trial?

The views in this thread of some of the members here don't surprise me - (the one-time schoolyard bully?.....Another who was the one the schoolyard bullies picked on and is now getting even by becoming part of the herd?) - but I'm really surprised that there are those whose views I respect (altho I may not agree with) also applauding the deaths of individuals who have been imprisoned without a trial or hearing.

Do you people really want the government to have the power to arrest and imprison anyone they wish to for any reason, without a trial?
