Yeah - if you are a teacher you ALWAYS leave the door cracked open, never alone with a kid.
Those kinds of kids almost always have genuinely experienced sexual abuse elsewhere. I’m working with a child who does exhibit that kind of behavior - propositioning adults/other teens and then claiming assault when rejected. The thing with kids and false allegations is that they are usually wildly inconsistent - as long as organizational safeguards are in place, it’s usually easy to verify that the claimed event didn’t happen. It is a STRONG indicator for previous experiences of abuse though.
This case is not at all consistent with what false allegations look like.
