The conceit here is all footage is real police bodycam, Ring front-door spycams, phone footage, etc. I'm dubious about the how much of this was filmed before the events, and how much staged, but it's badly shot enough in many places to be possible. The Facebook captures are kind of gross, the fake SMS reenactments with fake misspellings and retyping are weird; "Shanann"[sic] was as bad at spelling everything else as her own name (it's normally pronounced & spelled "Shannon")?
It's creepy how much people share, without saying anything of substance. Self included, of course… you know what code and games I release, and my snarky media reviews, but I don't tell you anything else. On Fediverse, I mostly share jokes and comics I've found, and bitch about code.
The police station footage is really the disturbing part, as always when showing conversations with pigs: The touchy-feely-cop and bad-cop routine, no lawyer, cameras left running during "private" (but not protected by lawyer) conversations. Obviously the first and only words you should utter to cops are "I have no comment. I want my lawyer. Am I free to go?" Am I the weirdo for being incredibly skeeved out by pigs rubbing someone's shoulder to try to make them confess?
The "cashless economy" is an incredibly bad idea, and this shows why: Every step anyone takes is recorded as a bank charge. If you carry cash (as I mostly do), then only your dumb online purchases show up, which are probably not too incriminating.
The reveal of the murders, such as it is, is incredibly badly presented, but they just didn't have any footage to present it. And there's not enough "character building" to tell anyone why. I don't believe the statement accepted by the court, but no better information is possible.
In the end, this is a horror movie about people oversharing.
