The law of the land (the USA anyway) says that if you have a conversation in a restaurant, there is no expectation of privacy. If you have a conversation at home, you do have an expectation of privacy, unless I consent to having my conversation recorded. As soon as you send/receive information in a public place there is no expectation of privacy, from a legal perspective.

If you send/receive packets of data over a public connection, i.e. the internet, somehow you are expecting privacy? Hmmm. (notice the thoughtful pause) If you want or need privacy over a public medium, it seems simple to me. Use encryption.

Don't get me wrong, I hate big government and big government's intrusion into my personal life. But, I also do not see my internet activity as a personal/private activity. There are just too many people involved. Webmasters see me visiting their site. My ISP knows where I go and what I do. So, I assume there will be others knowing that stuff too. There may be dozens of people 'knowing' what my internet activity looks like. No, I do not like big brother recording everything. It will, however take an amazing database to house all the data while waiting to be filtered and I am doubtful that the end result will accomplish what they are striving for.
