If I or somebody else was the victim of a crime I would 100% support using every available source of information to solve that crime. I think we need adequate controls sure, but mostly we need to increase trust in government and police forces so we know we can trust the relevant people with our data.
There is epic fear in the US about the government. That is the actual problem. Now the US gov is a shady piece of shit, so a lot of that is well founded, but that is the root of the problem. Solve that problem and actually trust the people who are supposed to be responsible and in charge to do the right thing and this data problem stops becoming as much of an issue. And no, building some kind of philosophical zero trust system is not going to solve anything, it is a prison you'll end up living in.
Encourage transparency in Police forces and Government with strong legislation and strong support for whistleblowers and punishment of infractions and you have yourself a system that people can begin to trust.
