"Why don't the FBI and CIA DO something?"
Well, you all asked for it.
People seem to have forgotten how massive barriers to prevent abuses by the FBI were raised during and after the anti-war movement. People seem to have forgotten the multiple laws and regulations preventing the FBI from acting internationally, and the CIA from acting domestically, and are now wondering why the two weren't exchanging data despite this firewall.
Now, all bets might eventually be off, and everybody given free reign. For sure, it will be easier to catch the bad guys.
Or anyone else.
I hope we're ready for it.
