Do we need to compare PTI with PMLN? What kind of comparison it is. Khatak has done some thing wrong then why can't we simply say that this wrong instead of comparing his act with some one else.You are right try to harm someone is a crime and a person who hurled shoe on MNS must be punished by government not supporters of MNS. Was he not tortured by PMLN supporters before handed over to Punjab Police? Even there is a video people went to Police station to harm the attacker.
