"Two counts of 'endangering a student'?" he asked very surprised. "When I have endangered a student at the school?"
While the question was directed at Harry, Hermione answered. "The most obvious is the endangerment to the entire school population. You said that a most painful death awaited those who ventured onto the third floor. Since no classes go there, that has nothing to do with our education and you're doing something non-school related that puts students at danger by having it here."
"As long as everyone stays away, there is not an issue, Miss Granger," Dumbledore stated as if it should have been obvious.
Harry chuckled and everyone looked to him. "Headmaster, the best way to get us students to do something is to tell us not to. I'm aware of more than eight students who can tell you about the Cerberus behind the locked door."
McGonagall paled. "Are you serious, Mr Potter?"
"Yes, Professor. It's a common conversation in the common rooms, or at least in the Gryffindor and Ravenclaw houses. I don't care too much as I know I'm only a first year and can't get past it, but some of the older students are researching it … and not just Gryffindors either," he hastily added.
McGonagall glared at Albus. "I told you that was a bad idea. You need to send it back to Flamel."
