This assassination attempt was not a normal one. This is not an assassination attempt where when the person targeted lives and is not killed and we breathe a sigh of relief and move on. This is different. Something must be done to arrange for the termination of Kimberly Cheatle as head of the Secret Service. She can NOT be director of the Secret Service.
The entire chain of command right down to the agent in charge needs to be given janitorial duties. For the rest of their lives.
