I just don't see the concern. Other than this being another ploy to frighten the masses. Are we going to ban government employees from FB, Twitter and other social sites so they don't come across that crazed Idaho militia member or Ron Paul supporter with a KillObama site? Or Sayid Jarrah posting how to make a dirty weapon on FB from his cave in Afghanistan? How 'bout HuffPo and Drudge?
With the new millenia and new age of social inteaction, I applaud our intelligence gatherers for their gumption!
Don't terrorists use computers? Don't they use FB, Twitter, etc., and don't they post on HuffPo and Drudge, et al? Sure!
Don't get me wrong. It's a new age, with new methods of communication and new abilities to monitor potentially dangerous communication...it was all par for the course actually.
BUT, I just don't want to see it used to take heated lively debates, or even borderline stupidity...and find justification to arrest and detain, otherwise, well meaning, decent people or even dirt bags...who, at times, can become inflamed and talk stupid shit.
