The logic is simple. I am sure BJP people are not that stupid when they have been fighting all these idiots for this long.
If a lay man can figure out what CNNIBN is like then why not BJP? They made one of their own as witness. But this animal Sardesai played even worse & did not air it. BJP never denied they don't have a copy. They simply want to have it come from the official source & so they can avoid all these bikering by the yadav rogues.
The world knows now that Sardesai had a tape, & he gave it to another crook called Chaterjee.Now that idiot is also a witness & so is government. These Yadav crooks had to play another dirty low game which they have started now.
