I was pondering : what would be the best way to use the blockchain to fight crime, and here is the concept I thought

Imagine how game breaking that would be : you could track if there is a group of suspects spending too much time together and track their activities by looking at the log kept on a blockchain. People would be afraid of doing illegal stuff in an organized fashion since it would be easy to catch them doing it if someone suspect is in their group.
However, I know this would be used by the governments (especially the U.S.A. ) to spy on people doing nothing wrong. But aren't those people already spied on?
What are your thoughts on it? What solutions do you think could help bring this idea to life without giving too much power to the government?
