Regardless of the frequency of prosecution, perjury is still a crime that is punishable by fine and/or incarceration, regardless of whether one is a lawyer or not.
Not under 18 USC 1001 it isn’t, if one is a party or counsel to a party.
You gotta have a statute, or the inherent power of a court to punish for criminal contempt, before you get to start putting people in jail.
None of these folks is going to jail simply because they did not fully disclose the nature of the Steele dossier to the FISA court. That’s my projection. If shitbags like Michael Vecchione don’t go to jail for what he did to so many defendants, these folks certainly won’t go.
