The only thing you've said is that a Kosovar Albanian told you that a KVM patrol was stopped by the KLA on the 15th.
That does not equal the KLA manipulating the crime scene at Racak.
What does equal a scenario is the witness statements (from Pro LDK villagers, per you), forensic evidence, and the autopsy results - all of which point to Serb culpability for the killings.
Now, do you have anything to bring to the table other than the KVM patrol being stopped by the KLA?
