You are right...It was discredited.
Here is quite excellent overview of this act of terror as juxtaposed by what happened in Bosnia.

The article in question mentions the extra-judicial killing of 2500 people.
I have seen enough of massacre-denying in previous Balkan threads to know where this is going. Perhaps you actually believe no that murders were committed or perhaps you don't care that the "wrong" people were killed. I don't want to keep company with people who fall into either of those camps. Good day.
