The FBI is involved with these nuclear disaster training exercises every year. The DOE puts these on to train the FBI, military response teams, local SWAT and state emergency response personnel. A different area is chosen each year. I was part of the exercises for the DOE for many years.
Having said that, who knows what kind of s^^t the DOJ might try to pull. I no longer have ANY respect for those A$$holes, except the FBI Special Agent Bomb Techs. I would trust any of them to save and protect my family.
The regular special agents are arrogant dicks. Every one of them in my experience live to push people around and let them know that they are the ones in control and can F^^K up your life.
The only FBI agents I've ever trusted were Mulder and Scully.
