Edward J. Black: “The amount--what you learn by being able to monitor precisely someone's location over a period of time can reveal all…”

If we go to the concept that the data used by technology companies to perform their functions are just business records, then a massive amount of information about everyone becomes available under a lower standard.

I firmly believe that the United States must continue its full-throated support of freedom of expression worldwide.

The level of intrusion, unwarranted and unconsented intrusion into people's private affairs--their location, their sensitive data, a variety--is something that we need to guard against.

The fact is, modern digital technology has great benefits, but it does open up the potential for great access into people's private affairs.
