Notice how Herman Cain’s “troubles” stopped the very minute he stepped down from his Presidential run? THey seemed just as active as Cosby. In a case of he said/she said, innocence until proven guilty isn’t just a good idea. It’s a requirement.
Certainly it should be investigated and if true, he should be prosecuted or if the statute of limitations is over, he should be publicly castigated often and vigorously. If innocent, he should be left alone.
When Cain stopped his run he also stepped most of the way out of the public spotlight. Not much reason for anybody to care anymore.
