I always figured that the Veritaserum that Umbridge attempted to give 
Harry wouldn't have worked even if he did drink it, because Snape made 
it for her, and Snape is a member of the OotP and a veteran memeber of 
the Hogwarts faculty. Just like he "convieniently" doesnt have anymore 
Veritaserum to offer Umbridge after catching H & H in her office.  
Love that scene.  Am I wrong about Snape and the potency of the 
Veritaserum in Umbridge's tea?
