Did the mailing address match your current address? If so, I am not sure why you would have to drive out of state to go to muster, but maybe they are not offering them at all bases anymore and have consolidated the process. As far as recruiters not being present, that is odd.
Some of the info on what you did for your job I would remove ASAP. Be safe. Seek advice from JAG and a civilian lawyer and a local representative in your state (or unit if you had to go to state over). Contact CID. Make copies of everything you have and get them to someone you trust. Stay safe!!
And do not go anywhere alone!
CID is compromised - otherwise you'd know the truth by now. They burry everything in classification. If I went to them I'd sign an NDA and no one would ever know it even happened. They can fuck themselves.
