How is this for an idea, following on"Even if you'd prefer the FBI reading a few innocent emails without permission to a drug trafficking ring operating in your hometown"
How about the FBI setup an opt-in program. I'd let the FBI read all my emails and dig through every old excel file if they want. They could check my GPS location whenever they want. Heck, if I was lost or in trouble, I'd want them to. My phone mic, turn it on and listen in all you want. If I need help, they will hear me ask for it and hopefully send an office.
I bet a lot of people are in the same boat as me.
