Wouldn't that be a huge privacy issue?

That feels like it would be a logistics and a just in general nightmare. Does every single individual have an account where they're forced to stream their footage? If not and it's all being uploaded to a single channel for a department, who's in charge of the task of uploading the footage? Who'd even be willing to spend their days doing nothing but uploading footage when your departments internal internet connection comes to a crawl speed because of the person(s) who has/have to upload the footage (because you just know they certainly ain't paying for them to have their own private network for this in most areas)?

In theory it sounds great but in practice it just sounds like a nightmare. Not defending the police but it just doesn't seem like a task they'd be willing to take up because of all the work they'd have to put in to make sure it works.

That, and the money they spend doing something like this could obviously be used on something more pressing, like shooting a black man because he didn't get down on the ground and worship the boots of the officer that killed him after being pulled over on suspicion of absolutely nothing (/s on this part)
