Sessions is a White Hat.
RR is a Black Hat, but is boxed in, i.e. [RR], or [[RR]], or [[[RR]]]. The [xx], in the box, can mean either removed from power, cooperating witness/actor, indicted, jailed, dead, disappeared, vaporized, or more seriously removed from doing bad stuff.
White Hats can be boxed in temporarily, i.e. [JH], meaning their work is in progress, but on hold (such as sealed indictments, not yet executed). When the box is opened for the White Hats, i.e. "]JH[", then the SHTF for the bad guys.
When a Black Hat is boxed in, i.e. [[RR]], it's possible he is "caught", and pretending to work for the White Hats, but is highly susceptible to Arkancide by the CABAL. So sad.
Others here might be able to explain this better.
Nope.
That's about the best I've seen.
