I really liked this! I think, sadly, though, the Ministry would side with Umbridge. Also, I know it's terrible, but I would have liked some Snape in there (I also know that that wasn't part of the challenge...) because he would have supported the Wolfsbane argument in favor of werewolves, but then turned around and pointed out that it all depends on the werewolf actually taking it, and possibly even pointing out Lupin's own lapse... I think he'd suggest passing the bill, but with a Wolfsbane clause that makes it mandatory for all registered werewolves to appear at the werewolf office or something so that someone can witness them taking it, and that they should be arrested or locked up if they don't show. That seems very Snape-like to me... Sorry for the digression! The story is great.
Snape's voice was wonderful here -- It was obvious who was speaking immediately! I also think that both positions are believable. I know someone said they didn't think Snape would disagree with Dumbledore, but I think he would, especially in this case.
I loved the hints in Snape's letter about the Sirius Black escape. Very nicely done!
Ah, that was wonderful! I love Anne's comments about Crabbe and Goyle. I also really liked Dumbledore's response: in particular, the comments on wizarding money and the recorders hurting Mrs. Norris' ears!
