Epstein's several homes were raided by the police and FBI. You might ask them what they've done with the items they removed.
I read up on the background to the Sharon Tate murder case. It appears a lot of material was removed from the Tate/Polanski residence by the investigating cops and placed in secure storage by the LAPD and maybe the FBI while they assessed its relevance to the case (or so they said in public). On one level, this was probably right and correct - among other things, there was a fear that unscrupulous journalists or just plain souvenir hunters might get there first, and anyone in Polanski's position at a time like that deserved a degree of care and enhanced privacy.
On another level, there were whispers of sex tapes, audio recordings and "private films" in which identifiable members of LA's upper strata (including the political elite) could be identified in sexual activity, sometimes including under-age people. Given Polanski was in the spotlight for this some years later, this does sound credible,
So the obvious questions are - can we be sure
all of this was released back to Roman Polanski after police inspection determined it had no relevance to the Manson investigation?
Who knew it was there and ordered this stuff to be gathered into safekeeping when there was a risk that, for instance, investigating journalists might have eventually found it? Who had the power, formally or informally, to direct the LAPD on this?
While it was in "secure storage", were copies or transcripts taken, and if so, by who and for what purposes?
And what would the police procedure have been if, while investigating a multiple murder, they inadvertently discovered the grieving husband was routinely filming himself having sex with underage girls - how to proceed in this case?
While a few decades separate Polanski from Epstein - are there links? Is there a "tradition" of this sort of thing in Hollywood?
