Hi! I just got to the police department portion, and I was confused as to why they wouldn't create a local network for information to travel. If it's used as a wired connection as well as a private connection between the various controlling organizations, it would be a far more efficient and safe way to pass along information as well as store it.
If it were to be a space issue, they could probably convert an unused storage facility or basement into a server room to house and transfer the information as necessary.
