Earlier quoted context omitted.
Good, then prosecute him for the actual crimes he committed.
I'm confused; you seem to be arguing two opposite positions. You say that a civil defamation lawsuit by Dominion is suppressing dissent, and that Giuliani should be criminally prosecuted for unspecified crimes. You do realize that the latter has a much larger chilling effect, right? It's not consistent to argue against a civil case for being too chilling, and then argue for a criminal case over the same conduct.
In case someone thinks this is splitting hairs, I fully support Dominion suing Giuliani for his alleged defamation. I would be somewhat horrified at the Attorney General attempting to put him in jail for it, ceteris paribus.
