This week, Hollywood continued reckoning with onscreen depictions of racism and police violence. The Paramount Network pulled its long-running police reality show “Cops,” while A&E canceled its hit show “Live P.D.” Meanwhile, HBO Max has pulled “Gone With the Wind” from streaming for glorifying slavery. The network says it will return at a later date with a disclaimer denouncing the film for portraying slaves who remain loyal to their masters even after the end of slavery.
