ANDREW C. MCCARTHY: Robert Mueller’s Plan.

No prosecutor builds a case the way Mueller is going about it. What prosecutor says, “Here’s our witness line-up: Michael Flynn, George Papadopoulos, Alex van der Zwaan, Rick Gates, Paul Manafort, Michael Cohen. And what is it that they have in common, ladies and gentlemen of the jury? Bingo! They’re all convicted liars.”?

For a prosecutor, like any trial lawyer, what the jury thinks is at least as important as what the law says. If the most memorable thing the jury takes into the deliberation room is that no one should believe a word your witnesses say, you are not going to convict the lowliest grifter, much less the president of the United States of America.

As a prosecutor, you build a case by having your cooperating accomplice witnesses plead guilty to the big scheme you are trying to pin on the main culprit. After all, what makes these witnesses accomplices, literally, is that they were participants in the main culprit’s crime. That’s the scheme you’re trying to prove. So, on guilty-plea day, the cooperator comes into court and admits guilt to the same conspiracy on which you are trying to nail the lead defendant.

That gets you 90 percent of the way home.

But if your intention is to smear by implication, rather than build an actual criminal case, you’d go about it the way Mueller is.
