I have defended the good agents in the FBI before but then lost faith that there are any left. The occasional whistleblower gives me some hope that there are still some good agents working there though the number is small and shrinking daily.
I am also convinced that there are no essential duties left to be performed by 99% of the federal law enforcement agencies. With the exception of border patrol and the Coast Guard, we could do away with ALL the other federal law enforcement agencies by simply authorizing the states (and their political subdivisions) to enforce federal law.
