That's a great question.
I tend to agree with Mr. Rankin. There has to be a timeline. We need to require people to keep that metadata to a certain level, because it's not as though a crime happens and we immediately arrive at the opportunity to collect this stuff. Crimes, and particularly more serious ones, don't have a statute of limitations. We're not talking about theft from a grocery store. We're talking about child exploitation or transnational crime, and that information can become incredibly valuable to the investigative community and policing.
Of course, I understand people's concerns about it in terms of a private citizen who commits no crimes. I understand that, but the reality is that nobody is going to look at their metadata, because they aren't doing anything wrong from the policing perspective. When you're a criminal and you're targeting our communities, it's the longer the better for us.
