The smart brevity on last night’s 13-page sentencing memo for former national security adviser Michael Flynn, in which Robert Mueller recommends no jail time because Flynn was so helpful:

First: The good stuff is all redacted!

Second: Flynn has helped the Justice Department on three separate investigations: Mystery Criminal Investigation #1, the special counsel’s probe, and Mystery Investigation #2. It’s possible the second probe is a counterintelligence investigation rather than a criminal investigation, in which case its results will never see the light of day. Solving the mystery of Investigation #1 is going to be job numero uno for everyone today.

Third: Flynn appears to have set an important example. Mueller writes that his early cooperation “likely affected the decisions of related firsthand witnesses to be forthcoming with the SCO and cooperate.” Who are those witnesses? What are they saying? Ahhhhh!
