In an exclusive interview with the Minister of Magic himself, Kingsley Shacklebolt said while it was somewhat suspected Mr. Malfoy might lash out, he nor the other Ministry officials were prepared for the onslaught at the Gala. "Mr. Malfoy had been under close watch of my now deceased assistant, Percy Weasley. Weasley had reason to believe that Malfoy was planning this heinous scheme for quite some time. He was angry about his restricted magic and probation, about the health of his imprisoned father, and more recently about the passing of his mother. Rather than seek the counsel of friends or his professors, Mr. Malfoy unfortunately chose to retaliate against the Ministry, wrongly blaming the system for life problems that were only a result of his own dangerous and selfish actions as a follower of Voldemort during the War."
