I disagree.  Co-conspirators is a legal tem which can cover everyone from the guy she hired to set up her system to her Chief of Staff (Weiner's wife).  And 'personal  profit' is not just money, ideals and beliefs are in there. too.  In the spy game they use the acronym MICE.  Money, Idealism, Compromise and Ego/Excitement.  (Learned that stuff in the ARMY)  I can see at least two of the four in the Hillary stuff/staff.

Prosecution beyond a reasonable doubt in a criminal court is a standard hard to meet.  That's why Martha Stewart went to jail for lying to an FBI agent instead of insider trading.  That's why the Feds came up with a Civil War era statute to prosecute the Bundys instead of treason.  (And even that didn't work out.)  And everyone doesn't have to be involved or even aware of everything going on.

Hillary had loyal minions who believed in her and her goals and 'the end justifies the means' takes care of a lot in that situation.
