Evidence: “We know you had this data based on emails between you and X entity, who already gave us emails and confirmed it was with you who they were communicating. We know you destroyed hard drives based on the fact that we found hard drive remains in your trash within 24 hours of receiving the subpoena. Cough up the data or face prison time.”
It’s not hard to solve for X when you know the rest of the equation.
Destruction of evidence is also a crime in most places.
