I'd be interested to know what people were expecting from MIT (and would also like a public statement).
The dockets (1) suggest MIT made the poor (perhaps incidental?) decision to involve the Secret Service, at which point the evidence became part of a federal investigation.
I think the paragraph about MIT's "tepid" interest in the investigation is telling.
