Who decides what's in the "greater interest of law and order"?
I'd like to see s system of flawed people making mistakes from time to time. What we have is some people to whom the law, for all intents and purposes, does not apply. And you have people.cheering that on. You can't serve the greater purpose of law and order under those conditions, that's the exact opposite.
If anti-trumpers could let Trump off the hook (for being the most investigated person in history with nothing to show for it) as easily as you are willing to let repeat offenders off the hook, then I could start to accept your premise as possible.
