Spicuzza has been criticized for the use of pepper spray on seated, peaceful students at a protest in November. In an e-mail message, she said: "As the university does not want this incident to be its defining moment, nor do I wish for it to be mine. I believe in order to start the healing process, this chapter of my life must be closed."
