Wendy, do you remember Snape removing points from Hermione for being 
a show off know it all?  Or the time he removes points from Harry 
for having a library book outside of Hogwarts?  Any time Harry or 
friends are caught defending themselves against a Slytherin, be it 
provoked or not Griffyndor always is the house to lose points.  
Even McGonagall seems to favor Slytherin in one punishment, she fines 
her own house 50 points per student and Malfoy only 20 points for 
the same infraction. Sounds to me that a structured fining system 
needs to instated so every house gets the same punishment no matter 
who catches them breaking the rules.  And yes Harry has had his butt 
saved by DD on many occasions when Snape wanted to toss him out of 
Hogwarts.

Severus "from evil" Snape
