FBI Misses Another Mass Shooter, Middle East Heating Up, Banks Melting down Again

Looks like the FBI was told about the mass murderer before he went on a rampage that left 17 dead in a Florida high school this week. This isn’t the first time the FBI was tipped off about a mass murder plot and did not stop it.  The shooter that killed 9 in a South Carolina church was allowed by the FBI to buy a gun.  The FBI were tipped off about the Boston Bombers, the Fort Hood Shooter and the Pulse Nightclub mass murderer all well ahead of time.  Is this incompetence or “too stupid to be stupid”??  Should someone be fired?
