Sure, but there are many avenues of investigation that were previously available to law enforcement and still are. The question in my mind is does having effectively unbreakable ways to store data do more harm than good? I think it does more good. There are still tons of options available to law enforcement that worked in the past to catch criminals. The sheer quantity of data that is stored about each one of us opens up a lot of potential for harm (which has been massively abused). What we're talking about is simply a return to the state where if you want to gather data about a person you have to mostly start at the point when they become a real suspect not before. You also can't get a warrant to peer into the other unbreakable data store - a suspect's mind. If there were such a technology would it be ok for it to be warrantable or should some things just actually be private?
