In reply to another query, Swamy said those who had raised slogans in praise of slain gangster-turned-politician Atiq Ahmed here on the previous day were "bringing disrepute on themselves". "They were being foolish. It is well-known what type of man Atiq was. His murderers have also been caught and they will face the appropriate action. We need not worry much about such slogan shouting. If the slogans were anti-national in character, the administrative machinery may take cognisance and appropriate action," said Swamy.
