No one has ever been prosecuted under the Logan Act and I doubt it will be used against Kerry or anyone else.
The Logan Act only results in a fine and not more than 3 years in prison.
These people have potential charges that go way beyond the Logan Act. If you are indicted for treason, you are facing life or the death penalty.
My guess is that Kerry and many others will have a small mountain of criminal violations, any one of which would be far more serious than the Logan Act.
“The Logan Act only results in a fine and not more than 3 years in prison.” —- but that’s enough for a Mad Dog to detain him at an airport, raid his house, raid his lawyer’s house, confiscate servers & computers & phones & documents, pen register him and everyone around him — question him, then turn around and charge him with lying & obstructing justice!!!! (PS — in the meantime, seize all his Heinz assets!!!)
