The very nature of cloud storage means investigators may not be able to access a logical hard drive somewhere to recover the evidence. First, the sheer amounts of data stored on servers make this close to impossible. Second, there are jurisdictional issues.
Not only may information be stored outside your jurisdiction, but it may also be stored in another country altogether—one with different criminal and privacy laws. Accessing evidence of a crime in the United States may actually mean committing a crime in another country.
This is a problem for local law enforcement, which has been left largely to its own devices when it comes to online crime. Only Internet Crimes Against Children (ICAC) task forces have clear direction from the federal government on how to proceed.
Hence it’s easy for local police to kick Internet crimes up to regional, state, or federal task forces. But, more people coming online means more crimes being committed against people in local jurisdictions both large and small. Law enforcement at every level needs to be able to respond.
