You are wrong. You do not have to "enforce" it, just defend your status and jurisdiction.

I'll have to read through that. But I've seen, more than once, how the jurisdiction was "managed" to fall where the prosecutors want it to fall.

One such example I read about was with a dark net market where investigators tasked someone in DC to buy a banned substance so they can claim there now was a "victim" there. They knew they'd get a better chance at conviction in DC. And it worked.
State declares its own actions as above board, et voila, you can have your jurisdiction and conviction.

Now come the other question: if somebody PLEAD guilty, so in other words recognize the wrong, WHY in the hell I have to try to pardon him?

There's nothing to pardon. I never asked for that.

virtue signaling that serve absolutely nothing.

Agreed.
