"If you break into their house and leave some personal items along the curb, like nude photographs? I'm probably going to gawk at them as I drive by. I don't like the fact that I do it, but I am human. You are still a criminal, and as long as I don't start sharing your personal items, I'm not. I'm just a schmuck."

What you've just unknowingly (I hope) done is encouraged continuously violating people's privacy, property, and physical health using powers of state just in case something is found. Given most are innocent enough, that means innocent people will be hurt constantly to find some extra guilty ones. That's ridiculous from a moral perspective.

It also assumes the cops are all good: an assumption that's countered by existence of Bill of Rights itself. Not to mention steady stream of corruption cases, misrepresented evidence, lying to get fake confessions, and so on. Definitely not the kind of people that need any "right to ignore rights" if that should ever exist. Their incentive is to lock people up, not keep them free. So, the system should give us protection against that to force them to do it only when they have strong justification.
