In terms of the actual topic, I would be shocked if Williams approved of spiking the CECOT 60 mins story, if it is in fact politically motivated as many suspect. And I'm not particularly a "fan" of Williams or anything, though I've heard him on a couple of podcasts.
But you're also making this point about all signatories being hypocrites because you seemingly have a big bone to pick with the amount of blame Thomas Chatterton Williams portions to each side.
