Can Apple do the FBI's job better?

Our legacy methods of solving crime typically use historical data from the private user data space. Is it possible to identify crime from public data only? Does investigation of a crime necessarily require violation of privacy?

I think a sample test bed is nearing completion. With the advent of self driving cars, there might soon be enough of them on the road to record driving activity. In addition data from traffic cams should be publicly available. This is not private data and should not be restricted. The same way that the clothing I choose to wear in public is visible to everyone, so should public behaviors be visible. Didn't the founders of this nation also believe that punishment was a public event as well? (How rude that was)

Although there are orders of magnitude more data points than human eyeballs, machine learning has reached a point where it can sift and identify objects in events in public data streams that are illegal. Local police would appreciate this service immensely. (whose departments are chronically strapped for cash because politicians and other short sighted decisions lead to more consultants and decision makers than actual service providers). The data is free and only someone like Google or Apple could possibly have the resources to invent it.

I would so love to see the government submit to the pressures that private enterprise has been struggling with over the past two decades - downsizing, outsourcing and the elimination of money sucking incompetent middle management.
