Video of man being thrown off bridge in São Paulo shines light on police impunity

State's governor, a former member of far-right ex-president Jair Bolsonaro's cabinet, said critics can go to hell'

A Sao Paulo state police officer is seen leading an unarmed man to the edge of an overpass in an impoverished neighbourhood of Latin America's largest city.

Seconds later, the officer pushes the man, who falls backwards from a height of three metres into a shallow stream of murky, sewage-laden water. Three other officers can be seen watching the scene unfold, taking no action.
