After a 23+ Year Career of Military/Federal Law Enforcement my experience has been the FBI is always present before, during, and after every major Terrorist Event Globally. But Particularly in the United States.
Always "Investigative Work" that never leads to De Facto Action.
But they'll sure as shit do a raid on some political targets who dissent at calling the Truth out!
SAME SAME FOR CIA NIGGERS…
GFYS FBI & CIA! MAY YOUR ENTIRE ORGANIZATIONS BE SPLINTERED INTO A MILLION PIECES.
