Organisers claim seven million Americans came out to protest against US President Donald Trump on Saturday.
These are not police or official figures, and crowd sizes are always difficult to gauge, especially when aggregating numerous protests.
But it is clear the 'No Kings' protests at the weekend were cumulatively very large, and likely bigger than the original 'No Kings' protest in June, which had an estimated attendance of five million.
These are among the very biggest single day protests to have taken place in the United States.
So the indications are that the 'No Kings' movement is growing.
Prior to the march we wrote that the demonstrations were a test of the mood in the US.
A smaller crowd than June would indicate apathy or resignation among voters.
A bigger crowd would compel the president and his supporters to take note.
The crowds appear to have been bigger than June.
The president, who spent the weekend at his Mar-a-Lago club in Florida, paid enough attention to post an AI-generated meme on his Truth Social platform, showing him as a crown-wearing fighter pilot dumping liquid manure on the protesters.
Yesterday, the speaker of the House Mike Johnson said the meme was just satire, the president making a point in a humorous way.
He also said some among the millions of protesters at 2,600 rallies against the president had carried signs advocating for violence or even threatening death to the president.
Yet the evidence is very clear - these rallies were overwhelmingly peaceful.
In the nation's capital and in New York city, the police departments said they had not made a single arrest.
The same was true across the country.
There were a handful of arrests that happened after rallies had ended and crowds dispersed, but these fell into the "public order" category of arrest, not political violence or anything like it.

At the Washington DC rally - which organisers claimed attracted 200,000 to march down Pennsylvania Avenue to a rally point just below the Capitol - this reporter did not witness any aggressive behaviour or threats of violence, apart from one person carrying a sign that read "8647", a term that some Republicans have claimed signals a call to assassinate Mr Trump.
The number "86" appears to come from American restaurant and bar staff slang, meaning to deny someone service or throw them out. More recently it has been said to be a street gangster term for killing someone.
It was a pretty obscure term until James Comey, the former FBI head, posted a photo of some shells on the beach he found formed into the number sequence "8647" - interpreted by Republicans as being a call for the killing of the 47th president, Donald J Trump.
But it is pretty obscure and a bit of a stretch to call it an overt call for violence.
Apart from one person in a crowd numbering in six digits, I saw no calls for violence against Mr Trump or the government or the police or anyone else.
If they were there, I didn't see them (but I did spend a couple of hours with a cameraman looking for images for a TV report - in DC there was nothing remotely violent).
The crowd was overwhelmingly white, in a city where African Americans are the racial majority, suggesting many came in from the suburbs around DC, where most of the government, academic, business and military officer families live.
The size of the crowd in DC also obscured the professional protesters, the small but noisy groups, usually from the left of the political spectrum, who can reliably be found protesting pretty much everything in the capital on any given day, interrupting hearings in Congress, picketing the Supreme Court etc.
They were there, but the largeness of the 'No Kings' crowd revealed the smallness of the hard left protesters.
So this was a pretty middle of the road crowd, fairly middle-aged as well.
They struck me as regular, polite, American citizens concerned about the direction their Republic is taking.
And not trusting the politicians on Capitol Hill to sort things out.
Citing the opening words of the US Constitution, one lady said to me: "We the people have to save ourselves."
The participants were not worried about violent behaviour from demonstrators, but one participant confided to me a few days before the march that he was worried about agents provocateurs infiltrating the crowd to stir up trouble and give the government an excuse to clamp down.
Of course those fears did not come to pass.
The security presence was limited in visible terms to the several police forces that operate in the District of Columbia, mostly the Metropolitan Police, providing the usual level of large event policing that they deploy routinely for the many large-scale events that happen on the National Mall.
Or at the big sports venues on match day. Just normal crowd control.
Police departments around the country have put out notices in advance about "first amendment activities" taking place on Saturday that the departments said they would ensure happened in safe and peaceful conditions. And so they did.
But the rhetoric coming from the ruling Republican party in the days leading up to 'No Kings’ day was designed to put people off from turning out.
Dubbing it 'Hate America Day', some politicians talked up the threat of violence which they presumed 'Antifa', the supposed Anti-Fascist 'organisation' was planning to unleash under cover of the marches.
Governor of Texas Greg Abbott mobilised National Guard troops to go on standby around Austin, the state capital, in anticipation of violence by the far left. It never happened.
Instead of threatening and angry, the mood of the crowds was light, upbeat - lots of fancy dress (frogs and dinosaurs seemed to predominate in the inflatable costume department in DC), the signs either funny or serious, and lots about protecting the constitution, democracy and the rule of law.
Quite a few people also mentioned the anti-immigrant clampdown being carried out by ICE.
But it was noticeable in DC that the speakers who addressed the crowd did so from behind bullet proof glass screens - nowadays no longer a prerogative of the president.
I saw a couple of green-clad snipers on the roof of the nearby National Gallery extension.
In the course of four hours on the streets of downtown DC, I spotted a grand total of six members of the National Guard, all well away from the march route.
The big numbers in terms of turnout were in the cities of the northeast United States, and the big cities of California.
This is no surprise. These are the regions where most of the population live, and therefore where most of the voters live.
So these are the places where politics is most contested, and where it is easiest to organise a large crowd.
But crowds large and small did turn out across an impressively large swath of the territory of the United States.
And although estimating crowd numbers is an inexact science and is treacherous ground to venture onto, it does seem that this social movement is growing.
And that is a message to both the big political parties in this country, as well as the president (who, for the record, denied that he is a king in an interview with Fox Business last Friday, before the rallies: "They're referring to me as a king. I'm not a king").
In terms of the numbers, the latest polling average number crunched by pollster Nate Silver says that as of yesterday, President Trump has a net approval rating of minus 7.8, similar to Joe Biden at this point in his term, but better than Mr Trump’s first term.
He even improved slightly compared to the week before.
But where the president is underwater is in the economic questions - his supposed strength - with approval ratings of minus 27% on inflation, minus 14% on the economy, and minus 13.8% on tariffs.
Even on immigration, previously his strongest hand, he is polling a net minus 3.2%, down from plus 11% in February.
He slipped decisively underwater in mid June, as the ICE raids were ramping up (and coincidentally when the first ‘No Kings’ protest was called), and has stayed there ever since.
If the conventional politics of government and opposition are not working (and they aren’t - many of the marchers we spoke to complained about the Government shutdown due to Capitol Hill budget wrangling), then unconventional politics will step into the breach, as seen in both the way President Trump governs and communicates his actions to the public (neither of which are conventional) and now, through ‘No Kings’ days.
These street protests are perhaps the unconventional opposition counterpart to Mr Trump's unconventional way of governing.
The fears of a changed constitutional order expressed by many of the protesters standing in opposition to the ‘Unified Executive Theory’ of the president’s accumulation of power since 20 January.
As we approach next year's 250th anniversary of the Declaration of Independence, the spirit of the revolutionary constitutional order it unleashed appears to be in robust health.
What came through from the demonstrators we spoke to was that they were animated not by a hatred of America, as speaker Mr Johnson had implied, but by a profoundly American impulse to stand up for their constitution, and the liberties it promises.
And that is what gives this movement its real power - its potential to grow, fuelled by ideas that are drilled into every American from primary school onwards. Which frees the movement from party politics.
And that makes it much harder for the regime to discredit.
