Edward J. Black: “You are talking about a surveillance, monitoring capability which can be very detailed, very intrusive.”

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.

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

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.

If we don't establish firm guidelines to indicate that our private information is still private, even in our increasingly digital and interconnected age, Americans will end up forfeiting rights that we have held dear for a long time.
