As for the executions at GITMO....

Let me ask you this. You are the U.S. Government. You know that it is a military rule that once an execution is carried out you MUST offer the body back to the family or closest relative for burial. You will be forced to bury them if no one requests the body though.
Now the question.
Would you fly someone to Cuba, hang them and then fly the body back to the states to give to the next of kin or would you do all your executions as close as possible (within a few states) of where the body was going back to?
Yes because you do not want to spend money on a traitor.
Now lets say the family has to fly the body back because we don't want to pay for it. Don't you think people would start to notice if bodies just start showing up on planes from Cuba?
You bet they would, there are people who look for those things.
Common sense people. Use common sense.
Don't believe their lies anymore.

So if there are people being replaced by actors, and there were flights to Gitmo plus expanded quarters on-site, is it safe to assume there have been some arrests and people being held awaiting trial?

actors, masks, clones, tribunals, executions are all BS psyops to lull you into inaction thinking brighter days are ahead. Military doing squat

And what are you doing instead?

nothing that can impact the state of things now. You can say "I'm doing little things but at least I'm are doing something". Reality check, this mess is so huge that even if we come together it won't even dent the enemy. Constitutionally, nothing we can do, not even the military. On top of that we are against corrupt 3 letter agencies. So let's hear your suggestions?

My suggestion is do your research. The people who were supposed to be arrested were. You had not even heard about until Q. If you research you will see Hilary was arrested in S.A. in 2017. She should have been in Iran but she wasn't. When she tried to get back Podesta's plane was forced down. She sat in S.A. for almost a month. It is all out there published in liberal media as well as the media of that region. She was picked up by Military Intel. You can take it from there.
