A nice example of how to handle this with transparency and honesty. Carroll makes a strong case for accountability.
This thread makes clear that it’s reasonable to expect some explanation and soul-searching from those who were connected with Epstein.

Hey, my name is in the Epstein files! I've told the story before, but should probably re-up.
TLDR: never met the guy, never took (or asked for) any money from him, never visited the island. I was invited to the island, and said no.
It's not that hard to just say no.

If you’re trying to make sense of how people you know knew Epstein, it’s book agent John Brockman. He’s savvy enough to lay low, but we should be talking about him.
Friends don’t let friends sign with Brockman.

Yep. This angle shows that what Bovino said — and what Trump, Miller, and DHS wrote —are lies. They’ve again murdered someone trying to help neighbors, and are again slandering that person. Not to cover anything up, but to project their power and impunity. To suppress dissent, and to set an example.
Greg Bovino of Border Patrol begins press conference just now reading the previous DHS statement describing (among other things) Alex Pretti approaching agents in a way that is directly contradicted by footage in this video www.youtube.com/live/_zA-3M-...
NEW VIDEO: this appears to be the footage from the woman in the pink coat.

I don’t think it’s a complete coincidence that, yesterday, so many of us around the world were in awe of what Minneapolis was doing, and, today, the government brutally murdered one of those courageous people, just to show us they could. They think they’ll scare us into submission. They’re wrong.

That’s “below-zero temperatures” in Fahrenheit. -22 in degrees Celsius. Minneapolis, you’re amazing.
Thousands of people have been gathering outside the U.S. Bank Stadium amid subzero temperatures for a march against the federal government’s immigration crackdown.

Sydney, and Australia, are still grieving the attack on our Jewish community.
Since moving to Australia, one of my favorite things about it is that I feel so safe here. It’s devastating to know that that feeling has been taken away for our Jewish friends and neighbors. I’m so sorry.
