I'm sure that the sealed records contain the names of some authentic sexual predators. But I would guess that the majority of them involve gray area cases, with some outright extortion scams thrown in.
Congress had a process that allowed complaints to be filed on a promise of privacy. The secrecy would have encouraged some people to press sketchy complaints that they would be embarrassed to air publicly because their own behavior was clearly contributory. The secrecy would also have encouraged some Members of Congress to agree to settlements just to make nuisance claims go away. In other words, I would not for a moment expect that all of the sealed cases involve real abuse. But that is how it would be reported. It is inherently unfair to unseal these sorts of records.
This is the same Congress that had all of its computer files hacked by foreigners—and the CIA, right?
So, you are fine if dozens of national intelligence services as well as a wide variety of criminal organizations and lobbyists (oh, but I repeat myself :-) ) have the dirt (or alleged dirt) on Congress. You just don’t want the public to find about it.
If this information is released then the Congress-critters can’t be blackmailed any more on this stuff—and one slimy octopus tentacle is removed from the swamp.
Let them be humiliated by true or false charges released to the public—cry me a river.
