Any time Tucker Carlson issues a public apology, that's somewhat noteworthy. He did so last night, and in unequivocal terms, without excuses. You can catch this apology starting around the 10:00 mark, but watch from the beginning for the full context:
Here's the apology:
A lot of us missed this the first time around, and you are due an apology. And we're proffering it on television right now. We didn't see the obvious. If you empower the government to violate civil liberties in pursuit of a foreign terror organization--and there are foreign terror organizations--it's just a matter of time before ambitious politicians use those same mechanisms to suppress political dissent. And that's what we're seeing now. We should have seen it earlier.
This came on the same day that the FBI repeated its absurd evocation of the QAnon boogeyman--surely a low point for the Bureau. However, in fairness to Tucker I suspect this apology was in the works for some time, rather than a response to an event of the same day.
Which it was, it's welcome.
