The problem is that you'd still have to defend that this is non actionable in court, which against a politician? Good luck. "I will de-limb Politician by summoning space aliens with giant laser swords made from Alpha Centauri Moonrocks until Politician dies" wouldn't even be ridiculous enough if the judge and the politician are somehow in cahoots.
