"Documents obtained by ...shared with the Guardian"
"Internal documents [...] obtained and shared with the Guardian in 2021"
The only external item I found was NYPD "Social Network Analysis Tools: Impact And Use Policy" from April 2021 which does state how they collect and use social media data.
Similarly described & linked LAPD behavior also lacks evidence.
Anyone have links to these documents?
(I do not want to do this. Why do I have to do the work of investigative journalist? I just want to be able to trust them; alas trust is built over time and broken in seconds. [insert lamenting grumbling])
edit: documents can be redacted.
I rather the see the problem you mention with all the named ones, read pundits and people being interviewed on record...
