Should journalists be held responsible for what they say on their personal social media platforms? Jagrati Shukla, an assistant producer at Zee News, has been spewing venom against Dalits, Sikhs, Muslims, Mayawati et al in her tweets. Predictably, right-wing, casteist trolls on Twitter are lapping it up. But many are calling her out, including Supreme Court lawyer Sanjay Hegde, who tweeted on Tuesday that under the SC/ST Act, “this @ZeeNews reporter might be in serious trouble”. Zee News has had its share of questionable employees —Samir Ahluwalia of Zee Business who quit recently and senior editor Sudhir Chaudhary are facing extortion charges — but this flagrant display of casteism and communal hatred by one of its own is unprecedented.
