Also, most people don't know it, but most cell phones made in the past 7-8 years can have their microphones activated remotely. I learned about this in China. When we used to honestly talk about the Communists and the politics of China, we would take our batteries out of the phones (the only way to truly disable it). I comforted myself with the knowledge that it was just in China, but when I got home I found out that the same mechanism exists here.
We really have no knowledge of the true extent to which we may be monitored. If the warrantless factor is supported, then it will enable government to do any number of other things in secret.
This must be fought.
