Congress leader Sam Pitroda has stirred a controversy after saying, what happened in 1984, has happened. The congress leader then sought the BJP to explain its performance for the last 5 years. The BJP pounced on Sam Pitroda immediately, saying that people will not forgive the congress for its sins. The BJP also reminded the congress that its Prime Minister Rajiv Gandhi had also back then justified the 1984 anti Sikh riots by suggesting that when a big tree falls, there are bound to be tremors.
