> I'm not sure this principle is a good one. Almost everyone had probably broken a law or two (yes, this meane there are too many bad laws, let me know if youve an idea of how to solve that), so by investigating someone for some random thing they haven't done you've got a good chance of finding something. This de facto gives imprisonment powers to the police and prosecutors office, giving plenty of opportunity for corruption.

Well, that's not going to work out well - LEOs investigating a shoplifter should just ignore the corpse lying in the backyard?

It's just no going to fly - crimes are crimes, and if you want a crime to be not-a-crime then follow the legal process in your jurisdiction to make it so.
