The first one where the police uploaded videos and wanted viewer information is absolutely egregious and makes me wonder how a court could authorize that.
The next one, which I didn’t fully understand, but appeared to be in response to a swatting incident where the culprit is believed to have watched a specific camera livestream and the police provided a lot of narrowing details (time period, certain other characteristics, etc) appears far more legitimate.
They asked for information about a video watched 30k times. Supposing every person watched that video 10 times AND supposing the target was one of the viewers (it really isn't clear that this is true), that's 2999 people who have had their rights violated to search for one. I believe Blackstone has something to say about this[0]. Literally 30x Blackstone's ratio, who heavily influenced the founding fathers.
I don't think any of this appears legitimate.

No, that doesn’t seem very familiar.
