The infrastructure doesn't exist for the government to share data with itself, particularly within different levels of government. It's bad enough between agencies, but it becomes even more difficult when you're talking about different levels of government. Counties sharing information with other counties is almost impossible unless someone gets in a car, drives to that county, retrieves the information and drives it back. What the private sector does very well is build the infrastructure which allows that information, which is public, to flow freely across jurisdictional and geographical lines. That's the benefit that the private sector has brought to this process.
