Wow, A lot of subject matter here to cover.
Let me start with loss of privacy. I thought this country took privacy seriously.
Examples -
1. For the cops to come into your house they needed a search warrant.
2. To record telephone conversation, you need to tell the party being recorded that they are being recorded. Without that you need a court order to "tap" there lines?
These were laws that we passed as the times changed to "protect invasion of privacy without reason".
Times have changed again but it seems no new laws have been enacted. We simple should not be tracked or recorded without our consent unless a independent court decides there is reason to do so.
Laws were created to protect us while we are in a phone call. Why haven't we laws protecting the information passed on the internet?
Another change that has potential to rob us of our privacy are Radio Frequency Identification Devices "RFID". These are tiny electronic devices placed into everything we buy. They replace the UPC code and make it easier for retailers to scan items purchased. In theory you can have an entire shopping cart full of merchandise and as you move to the register, it reads all the RFID devices in cart without having to remove them from cart.
However; many of these devices remain in the merchandise forever. So when you walk in a store you are unknowing scanned. They can tell the coat on your back to the underwear (or lack of:laughing

you are wearing.
Changes are inevitable. Why has the United States not created new laws to protect our privacy. This country is all about "Freedom". Without privacy there really is no "Freedom".
