I am playing devil's advocate here, but mass surveillance can also save you.

Let's say your just broke up with your girlfriend, shortly after, her house get burgled and a bunch of jewelry is stolen, including some you gave her when you were together. A surveillance camera catches the burglar, a drug addict with a criminal record, he gets caught, tried and sentenced to 2 years in prison. The kind of case that won't get a news article, you may not even be aware of what happened.

Without the surveillance camera, you would be a prime suspect, and even if you don't get convicted in the end, there is a good chance for the police to give you a hard time.

Here is the asymmetry, if a surveillance camera prevents a wrongful arrest, no one will notice, because you don't notice things that don't happen. Only wrongful arrests caused by surveillance cameras will be noticed.

More surveillance doesn't mean more arrests, trials and convictions. These are limited by the availability of police forces, magistrates and jails respectively. Even with a total surveillance zero privacy dystopia, you can't have more arrests without the means to do so. What will change is on what grounds the arrests are made: video footage, a witness testimony, etc...

It doesn't mean I support mass surveillance (I told you I was going to play devil's advocate), but that alone doesn't mean more wrongful arrests as a whole unless something else in the system is promoting wrongful arrests.

There are legitimate concerns about Flock that don't involve wrongful arrests, such as misuse of data by operators, like for stalking, data security, which may leak to criminals, and usage for purpose other than law enforcement, like marketing. The fact that it is a private company funded by public money with dubious contracts is another concern.

Assuming cops actually present the evidence they have and don't hide it from the defense. The police and DA don't care if they put a guilty or not guilty person in jail, the 'tough on crime' faction that tends to get people elected cares about the number of people thrown in jail. The more the better. Throw 10,000 people in jail, you must be a damned good elected official and you get re-elected.

>you can't have more arrests without the means to do so.

Not exactly sure what you're trying to say... you can always have more arrests. Make more things crime. Pre-crime, thought crime, speech crime. When you run out of physical space you start stacking the prisoners 10 deep. When that runs out of space you start executing them and putting them in ovens.

This is what the presumption of innocence is supposed to do. If you have an alibi, then big brother doesn’t get involved. These are cultural problems that we do not need big brother’s benevolence to solve for us. We need better cultural systems of accountability; the problem is that those are _way_ harder to build

Police regularly ignore evidence that disproves their claims. They will not prove your innocence for you. It will still be up to you to pay the lawyer 1000s of dollars to do the discovery against flock cameras to attempt to prove your innocence.
