I think the difference is this time there were clearly unacceptable mistakes made that almost killed the president and cost an innocent man his life. It’s never as simple as blaming one person and calling for their resignation, but when you take on the leadership of an agency like SS, you accept responsibility for the actions of everyone under you. It’s just the way it is. It’s almost never fair, but you know going in when you agree to be the head/face of a huge organization that you become liable for things that happen on your watch.
