Umm, Gitmo was messed up. But, to be clear, the United States does not guarantee constitutional rights to non-citizens who have not touched US soil, so this is a bit of a canard.
> J6 detainees?
Despite rumors of hundreds of January 6th detainees languishing in jails-- the actual number is approximately 35. Most of these have waived speedy trial. Most of these have not been detained for a very long time.
A few are still undergoing legal discovery. It's a problematic set of circumstances: further, closely related arrests happen; without providing additional information on the new arrests to existing arrestees' counsel, convictions could later be set aside. In turn, this restarts some clocks. On the other hand, judges are getting frustrated and warning the prosecution that these delays are becoming excessive.

I can't find this detail in my copy of the constitution. 6A in particular specifies "the accused". It's true that most Gitmo prisoners were never actually accused of anything (because they had never done anything, in particular anything related to actions undertaken by Saudi nationals under the direction of Saudi intelligence personnel), and were eventually released without apology. However, any prisoner who ever actually went to trial would certainly be classified as "accused".
