Big Brother

It turns out that the FBI has found a way to remotely activating a mobile phone's microphone and using it to eavesdrop on nearby conversations. They don't need to get a hold of the phones. They simply download software to the phones remotely. And it works even when the phone is powered off. I wonder what other ways are used by the government to watch us without us knowing about it. If the government knows how to do it, I wonder how long it will take for the bad guys to gain this knowledge. That is if they don't already have it already. Do you know who is listening in on you?
