Yes, and that's what I meant by "let the courts sort it out later." The Constitution's not much help either way, being full of imprecise, hand-waving language and vague terms like "cruel and unusual." It was anticipated by the Constitution's authors that it would be of use only to a moral government.
Nevertheless, since there is no legal basis, there is nothing preventing the next government from prosecuting them.
I wonder if that's ever happened in the US? Does anyone know?
