Piecing together several sources to understand distortions is rarely linear. As a snapshot, in 2019 Nusrat Choudhury made a statement that everyday a black unarmed black man is shot by police.

I've seen that cited in several places and it was used as a means to undermine her in her nomination hearing for a position as a Federal judge in New York.

However, on checking, it seems as if the event where this alleged statement is said to be have been made is 2015 (not 2019), and Choudhury says that she didn't say it and there's no official record of her having said it.

Not entirely tangential to that, Douglas Murray claims:
A poll in 2020 asked Americans how many unarmed black men they think are killed by the police in America the previous year. More than a fifth of people who described themselves as “very liberal” said they thought it was over 10,000 unarmed black people in America killed by police every year. Among self-described “liberals,” around 40% said they thought that the figure was somewhere between 1,000 and 10,000. The actual figure was around 10. Meaning that liberals in America were off by several orders of magnitude. They had a completely wrongheaded idea of what America is actually like.

This is a summary of the survey:

This is the actual survey and report:

The very kindest interpretation would be that inadvertently somebody misreported Nusrat Choudhury and, given her status, it was accepted and treated as accurate. It was repeated often enough that it took on a life of its own across the years and in the context of some egregious events it was increasingly repeated in high profile media until it became fact through repetition.
Nusrat Choudhury denies saying it. Maybe it wasn't even the misreporting of her but someone else or a different misunderstanding is at the root of this.
There is plausibly a lot of motivated reasoning behind the survey.
Somewhere along the way, there does seem to be a lot of distortion and warping of views. And this feels like a distraction from the reality that being killed by gunfire is a public health issue in the US and it's one that disproportionately affects black and hispanic communities.
