Is Kerry Violating the Logan Act?

That's the big question:  Is John Kerry violating the Logan Act?  Alan Dershowitz says that he probably is.

Former Secretary of State John Kerry would be violating the Logan Act, if it was enforced, for secretly speaking with foreign leaders about salvaging the Iran nuclear deal during Trump’s presidency, Harvard Law School professor emeritus Alan Dershowitz argued Saturday.

No one is going to enforce the Logan Act against Kerry.    Why?  Because we have a two-tier system of justice in the US.  If you're a high-ranking Democrat, you are safe from prosecution.
