Senior Congress leader Digvijaya Singh on Monday said Prime Minister Narendra Modi was indulging in "drama" when he spoke about atrocities on Dalits and asked if he would take action against his own ministers who spoke against Dalit students."Great drama by Modi ji in his speech in Telangana about Dalit atrocity. But would he act against his own ministers who have spoken against Rohith Vemula and other Dalit students. He won't," Digivjaya tweeted."Has PM authorised the 'genuine' Gau Rakshaks to act directly? Under what law the 'genuine' Gau Rakshaks will stop the 'Feku' Gau Rakshaks?" he asked.Modi on Sunday called for protecting Dalits and for isolating and punishing fake "gau rakshaks" (cow protectors), saying they were destroying the country.His remarks were in reference to the flogging of Dalits by cow vigilantes in Gujarat's Una town on July 11, that has evoked widespread condemnation.
