Derek Chauvin was found guilty on all counts in the murder of George Floyd last night, the first verdict of its kind in a landmark case that inspired a wave of protests across the nation last summer against police brutality and systemic racism.

A few hours later, the St. Louis lawyer Mark McCloskey — who become known for standing barefoot outside his home alongside his wife last summer as the two pointed weapons at peaceful Black Lives Matter protesters — told Politico that he was considering a Senate bid in Missouri.

“I can confirm that it’s a consideration, yes,” McCloskey reportedly said Tuesday evening.

There are a host of articles today about the US reaching a vaccination tipping point at which the key challenge is no longer the supply of vaccine but the supply of people willing to take it. Like “herd immunity” it isn’t a binary, clear-cut moment. It’s incremental. We’re approaching it now and the challenge will accelerate over the next two to four weeks. In many ways this challenge is a product of our success. In January I don’t think anyone thought we’d have widespread availability and half of all adults vaccinated in April. But we did it.

I’m working my way through your emails on making sense of the post-Trump Era. Please keep them coming. (See the linked post for more details.) They are fascinating but like the topic itself they are hard to bring into focus. There are common themes but they are elusive. I will be publishing a number of them. But I wanted to start with this note from TPM Reader CC, who lives in Australia. It’s a very different perspective given that’s from someone in a foreign country on the other side of the world. But I found it very interesting as a window into what America now looks like from abroad …

“It’s not exactly my vision,” former President George W. Bush said of his Party during a live interview with NBC’s “Today” show this morning.

A very interesting backgrounder from TPM Reader AH on the specifics of the kind of stroke that killed Brian Sicknick …

Hi, Josh! This is a topic I really do know something about – I am consulted to see several patients for stroke every day. The news about Brian Sicknick having died from a brainstem stroke is a bit of a surprise to me, because they are uncommon in general, and for a young, healthy guy to have one raises my eyebrows. To die from one is less surprising – these are the most, or maybe tied for the most lethal strokes you could possibly have.

What are we to make of yesterday’s news that Capitol Police Officer Brian Sicknick died of ‘natural causes’? Sicknick’s death and to a much lesser degree the suicides of two other Capitol Police Officers within days of the insurrection are inextricably bound up in the story of that day and the gravity of those events. The Medical Examiner’s comments to the Post were themselves contradictory, at least in layman’s terms. Francisco J. Diaz found no discrete injury such as a head wound that would have been a proximate cause of Sicknick’s strokes. He also found no sign of acute respiratory constriction, which would be the standard sign of an allergic reaction to chemical spray which also could have caused a subsequent stroke. Yet Diaz also said of the events of January 6th and Sicknick’s confrontation with insurrectionists that “all that transpired played a role in his condition.”

What does that mean?

The pandemic has brought to a head the complexities of one very uniquely American problem: the emphasis we as a country put on individual freedoms, which, this past year, has repeatedly run headlong into the need to care for our fellow man during a global health crisis.

It’s also revealed in new ways a more depressing American problem: mass shootings.
