Privacy vs. Security

This topic has recently received a renewal in debate thanks to the "scandals" that the Obama administration has been facing due to the information leak from Edward Snowden. People have been complaining because the public and the media found out that the NSA has been tracking calls made by US citizens. Many people have been up in arms stating that this is breach in privacy and that the government is bordering on "big brother" territory if it hasn't crossed it. I truthfully believe that this is a breach in privacy for American citizens, but my argument towards the Obama administration is that they seem to support this ability of the NSA after Obama was a big proponent of fighting against this ability when he was a senator. However, this has been going on in our country since at least after the September 11terrorist attacks on the World Trade Center and Pentagon. Perhaps it was the timing, the American need for revenge, or just the US public not understanding what was changing, but the US bill that allowed for this tracking of phone and Internet search data was passed shortly after September 11 so that the US government could track, find, and capture or kill terrorists that threatened the United States. I did not like this then and still don't but we the people supported this ability so that we could feel "safer." The other side of this story is people are complaining about their privacy being taken and yet millions of US citizens have Facebook and/or MySpace accounts where they put everything about then from phone number, to address, and even where they are at every hour of the day thanks to location tracking in phones, so my question then is "What privacy are you looking to protect?" You have placed most information about you to everyone on the web. Now not everyone does this but no small portion do either. So tell me what you think of the argument over privacy vs. safety?
