My own image searches only turn up upside-down Canadian flags, "Fuck Trudeau" slogans, and stuff about "freedom". I'd have to think that if somebody really wanted to undermine them and had such a photo, they'd have posted it.

How bad is the reporting? I checked the NYT; https://archive.fo/Jny6X

It's not awful in any obvious way.

It does describe the protest as "mostly peaceful". As that phrase is a little notorious, I laughed a little. Since NYT staff spend a lot of time on Twitter, I imagine they know the significance. But hey, if it was peaceful and they said so, then they've done their job ok there.

The headline does have some negative connotations: The convoy "descends on Ottowa" (not, I dunno, "protesters gather to demand justice").

And there is one sentence that is incendiary enough that it really needs more context:

"Some of them carried Canadian flags upside down; at least one flag had swastikas drawn on it."

This invites the reader to draw one conclusion, but the meaning may be something else, as in my first paragraph.

So I'd have to see to be sure. But no photos are forthcoming.
