There obviously isn't a future without crime. This is just a tool to make it easier for police to do their job and deter criminals somewhat, but that is probably marginal.
There will always be kidnappings, there will always be property damage. Having technology available to make it easier to solve those crimes seems obvious to me.
I do not want to live in a society where police are watching everything I do in the name of solving minor property damage. "If you have nothing to hide, you have nothing to fear" is bullshit. I don't do anything illegal in my bathroom, but I do not wish to have a camera in there, even if it could solve a hypothetical crime.
If you want to put a camera in your personal toilet you absolutely can.
