Then you can start expecting SWAT teams raiding people's homes for downloading songs illegitimately (and yes, you'll even see more dogs and even innocent people shot in the process - just like in that "parody" video where the SWAT team shoots the kid who was downloading songs in the head at the end, which I can't find right now).
Some of these are not felonies yet, but they're working hard [2] to "fix" that "problem". Current and future surveillance technologies, used by either NSA, FBI, DHS, or even the police will make that ever easier and more "tempting" to do.
