I couldn't find much hypocrisy in their stance but I am fairly surprised that you had no problem believing the report & were fully convinced by it !
Perhaps the next time when the LeT posts through one of their Media Outlets - magazines, twitters & what not - about the Human Rights Abuses being committed by the Indian Army in IOK you'd have no problem believing them & would be fully convinced by them especially after of questioning they say 'So prove that it didn't happen' !
What you seem to be missing here is something quite elementary - An assertion is supported by proof to substantiate what is being asserted not accepted at its face-value & then asked 'give us proof' if you don't agree with it !
Thats like telling me that the blue pen right in front of me belongs to you & that I should counter that assertion by providing proof why doesn't it belong to you instead of you providing proof to begin with to substantiate your right of ownership !
Such are the foundations of 'Cognitive Reasoning' because proving a negative is a logical fallacy !
