That's why the importance of removing bad laws off the books, and reforming what we consider essential liberties is so important.
Yes, the observation state is coming as many have said, but how we apply it, and who has the power of checks is the the real question.
If every on foot police officer has a camera on their lapel that any citizen can log in to and monitor, if much of the technology behind the monitoring is transparent -- if the people ultimately control the monitoring and its usage is to detect weapons, explosives and true acts of terror...not petty things like teenagers with pot -- then I believe the coming 'monitored state' will not be as scary.
So the removal of bad laws. Maximum liberty in the privacy of one's house, and then crazy cameras and detectors for explosives and the printed guns et al is where I hope/believe the future can head too.
Call it the green tea party ;p
EDIT: In my world every printed gun, hell every gun taken out of the household needs to be transmitting its location so I can log on to a 'like google maps/latitude' type app and see exactly where any weapons in the public space are...and anyone caught by the monitors or an officer without 'reporting' on their weapons would face the severest of consequences.
On the counter side though, within the house hold, you can print and make whatever you want. You can do the vices you'd like, and you can petition for areas within the public space to do such things, as long as I can also see where it is taking place and avoid if I desire too.
