even after he plead guilty to prostituting a child
Reading the deposition, the lady in question was 17 at the time. Where we both are, this does not constitute a child as our age of consent is 16. That's why there's a legal definition of "underage" and "child", which you are misusing, and it's what got RMS in hot water for mentioning.
Minsky knew exactly what Epstein was and didn't care.
You mean after he was accused of the technicality of people underage in some areas of the world sleeping with older people? Really? Given the transcripts I've read, there's not a huge thing there. And the jail time was spent (or do you advocate for convicting someone of something then never letting them do anything again, which precludes the whole concept of rehabilitation, so you may as well throw people arbitrarily in prison for life, because they'll never be different?
Besides which the idea that a teenage girl he had never met before would suddenly proposition a much older man is ridiculous.
Oh dear. Oh dear, oh dear. This is so provably wrong in so many situations that it doesn't even hit the levels of an attempt to misdirect. It's provably false, so on to the next.
Even if he knew nothing of Epstein's crimes at that time, I think most people would be extremely concerned that they were about to be blackmailed or robbed.
Why is that exactly? As the old adage goes "Show your working".
