Right or wrong ? FBI Spying on you through face book myspace twitter?

Well have to say right, even though part of me does not like my privacy as a American citizen being invaded, but for the good, of catching criminals, terrorist, pedophiles, drug dealers, killers...etc. etc. I say best it is done, in a way I compare it, to our airports now. Yes people hate the lines, hate all their belongings checked, etc. etc. But how could anyone forget 9-11 ever..!!!!! Our airport security was lax way to long. Now we all must be aware, on guard, and take nothing we see suspicious as not worth reporting, our world as we know it in the USA, has changed. In so many ways.
