Pippin:
There are some notable discrepancies between the pensieve
account of Karkaroff's trial and what Sirius relates to Harry. 
First of all, Sirius says that Karkaroff put "a load of other people
into Azkaban in his place...He's not very popular in there, I can tell
you." But as we see in the Pensieve, Karkaroff was able to give
the Ministry only one name that it didn't have already -- Rookwood.

Who are the DE's who blamed Karkaroff for their capture and why?

  When we last saw Karkaroff in the Pensieve, he was on 
his way back to Azkaban, not freedom.  Maybe he thought of some 
more names later on, or maybe, as part of the bargain that freed
him, he agreed to take credit for revealing names that were actually
revealed by Severus Snape. Snape might even have testified 
 *as* Karkaroff, with the help of some polyjuice.

Then Sirius says that as far as he knows Snape was never even
accused. But in the Pensieve Karkaroff accuses him, and we learn,
from Dumbledore that Snape has been accused previously. It's
odd that Sirius wouldn't know this, and further very odd that
none of the people at the trial had children at Hogwarts and
would object to their being instructed by a former Death Eater,
something Sirius thinks would never be allowed. 

But why is it Dumbledore who informs the court of the previous
charges against Snape and their disposition? Shouldn't that
be Crouch's job? 

Unless, of course, that information was protected by Fidelius, and 
Dumbledore was the secretkeeper.
