'Position of trust' and 'very vulnerable people'
If the police are involved, we don't know what information Matt has, what age things have happened or anything. If Matt won't talk to the media because it would affect a court case, something has definitely been alleged.
One thing to always remember though, is whatever is said here is gossip, it is in fact hearsay, we can only have opinions of what is happening, and opinions of what people are saying.
The main clues that something possibly very big is going down, is the amount of silence that has occurred, and the amount of closing down of sites and other internet information that has been removed.
