That's a nice sentiment and all, but if the government, and particularly law enforcement at every level, has perpetually shown one thing, it is an aversion to oversight and accountability.
I have posted at length over the years of many, many instances of egregious violations of people's rights, including people losing their livelihoods, homes, and lives, over the years with the officers involved hiding behind immunity and legislative and union protections to try to avoid any kind of personal or financial consequences for their own negligence, incompetence, and malfeasance. And these things aren't, "I only had a split second to decide and made the wrong decision," but things like, "I had minutes, hours, or even days to do simple due diligence that would have prevented this, but it's not my fault," and, "I smelled alcohol on his breath until he blew a 0.00, and that's when I smelled weed in his car and realized his eyes were bloodshot. Yeah, there weren't any drugs in his car and his blood test came back negative for everything, but that arrest was perfectly reasonable," and, "I knew what I did was wrong and did it already, but I'm really a good cop." Case in point, the North Carolina police lieutenant who used Flock cameras to track his wife and was demoted but not fired. He's proven that he cannot be trusted, and his behavior could arguably be criminal, but that's not enough to get him off the payroll.
Until I see cops en masse asking for fewer protections, more transparency, and actual accountability instead of evermore roadblocks to investigations and punishment for misconduct, I don't think they or the government can be trusted to oversee and safeguard something like this. It would be great if we could have nice things like this, but since those who would use it seek to avoid accountability instead of welcoming it, we can't have nice things like this.
