“Most important, the special counsel found that there was no collusion between the Trump campaign and Russia, and that the president’s frustration wasn’t over fear of guilt — the typical motivation for obstruction — but that the investigation was undermining his ability to govern the country. The existence of such a motive is a strong counter to evidence of a corrupt intent, critical because corrupt intent must be proved beyond a reasonable doubt in an obstruction case.
In his report, Mueller didn’t resolve the issue. If he had been satisfied that there was no obstruction crime, he said, he would have so found. He claimed he wasn’t satisfied. Yet he was also not convinced that there was sufficient proof to charge. Therefore, he made no decision, leaving it to Attorney General William Barr to find that there was no obstruction.
This is unbecoming behavior for a prosecutor and an outrageous shifting of the burden of proof: The constitutional right of every American to force the government to prove a crime has been committed, rather than to have to prove his or her own innocence.
This is exactly why prosecutors should never speak publicly about the evidence uncovered in an investigation of someone who isn’t charged. The obligation of the prosecutor is to render a judgment about whether there is enough proof to charge a crime. If there is, the prosecutor indicts; if there is not, the prosecutor remains silent.”
