Check out my history. I bet it's boring as can be.
Sp what if theyhave an "interesting" history. Is this about choosing up sides or about trying to figure out how to run a Constitutional and Free Republic. Even if both sides devastate each other with fabulously destructive rejoiners and innuendi, (you leave my end out of this!) we'll still have the problem of how much snooping the gummint ought to be allowed to do in war time. People are still irritated with Lincoln, much less FDR, over this. Got an answer? I sure don't.
I just illustrated an example of data mining. Look at the history of posters, Jumping in red OK and Ninofan. Those records can tell us a lot about a person, and we should use them as long as they are not protected by the constitution as "private."
In the case of phone records and FreeRepublic posts, neither are protected "private" records. It is that simple.
