Because if the FBI had carried out a proper 911 investigation they would have brought thousands of Jews to arrest & trial by now, with their associates in US politics and news casting, while the JFK murder conspiracy similarly reached into the highest levels of government, just like the stolen election.
There were no hijackers, the planes that struck the WTC Towers were piloted by remote control using hardware developed by Rabbi Dov Zakheim, who with Zionists Jerome Hauer and Michael Chertoff engineered the whole project!
So we know the FBI is under firm enemy thence ZioJewish control, and just as the rot is from within so must the solution come from within, picture junior FBI ops bringing senior officers and retired personnel to arrest & trial.
