Except in this particular case there appears to be a near-zero risk of anyone being "complicit" in bad police outcomes, given that it's opt-in, can only be used on a case-by-case basis, and it's the citizen who searches their own cam footage, voluntarily, and only in response to a specific police request about a specific case.
So, while at first glance at a headline, this might seem problematic, after reading the details, I'd probably be willing to participate. This can't really be abused to create any George Floyd-type situations.
