Yeah....Clinton used a variant of that thought train with his "it's under investigation, I gotta get back the American Peoples' business."
Nuremberg Trials 'looked backward'.....Israel's Adolf Eichmann Trial 'looked backward'....and on and on and on and on.....
And in a way, the Nuremberg Trials had no remedy looking backward. Nobody was or can be resurrected. The remedy in that trial was death and imprisonment for those charged and convicted.
I'm not saying the complaints have no effect. At the very least they put some people on notice, and to the extent the complaints are viewed as credible, some delegates may be turned-off to the wrong-doer, for whatever that is worth.
Politics, like government, is an exercise of raw power. The control mechanisms to hold that power in check are vague and unreliable.
