If you watched 100 videos of kitchen malpractice within restaurants in which:
- The acts of malpractice had broadly consistent characteristics
- The restaurants in question were all owned under the same organizational umbrella
- That organizational umbrella had the authority and exclusive control of the US government
And then drew the conclusion that maybe there were systemic problems that lead to these remarkably consistent issues, you'd be completely rational.
As for your other comparison between this and "the media" curating street interviews, I don't see the parallels at all.
A news outlet using a random interview with a person on the street as evidence that people are "divided over climate change" is clearly manipulative. In this case, a person is saying "Police are routinely using military equipment and force tactics against US citizens in disturbing ways. Here are 700 videos of it as evidence."
