An interesting point Carol. However, since Fudge was there and he 
has a history of NEVER asking the right questions, in fact, 
completely the opposite (so that I've always felt ESE!Fudge or 
Imperio'd!Fudge have to be the case), it doesn't surprise me at all. 
What I've never really seen any discussion on is why Sirius is 
laughing madly when arrested. This, presumably, meant that he was 
taken to be mad and carted off as quickly as possible and without 
too many probing questions asked.

Are there any theories out there I haven't seen about why Sirius 
laughed? It certainly seems to have been what damned him, in the 
mind'seye of the WW, to all those years in Azkhaban (see Ernie Prang 
and Stan Shunpike's convo on the Knight Bus). 

Could Pettigrew have hexed Sirius just before blasting a hole into 
the sewer by which he escaped as scabbers? (I don't recall a mad 
laughter spell), but there is a mad/uncontrollable dancing 
(tarantallegra) spell after all.
