Depends Boris. In a Criminal case, proof is required and must be beyond reasonable doubt.
In an employment situation (as YOU well know) the employer/interviewer has complete latitude to set whatever standards/parameters they choose.
In the case of a SCOTUS nominee, the standards are completely reversed. The accuser has NO standard, no hurdles. Just tell what they believe to be the truth.
The standards are on the accused. The accused (He OR she) must be held to the standard the American Public requires of the position.
In the case of a S.C. nominee, I think the 1st (MOST ELEMENTAL) requirement should be truth and transparency under oath.
Kavanaugh gave us neither!
