The grunt soldiers of the Taliban were in something appraoching "protective custody". No trial was ever called for is their cases. These people were carefully identified, interviewed and relocated. They are is the safest countries we could find where they would be accepted.

The remaining 270 include "the worst of the worst" such as "Chemical Ali", Saddam's master of nerve gas against the Kurds.

The term "go to trial" and "adjudicated" may be slightly different, and I leave that to tha lawyers here to explain, but people like Jose Padilla and other have had court hearings and they have had good legal council. The Guantanamo detainees names have always been a matter of public record and the proceedings are as transparent as can be expected.
