The riots you mentioned earlier happened to be pre-planned. The thugs hired by the opposition in Karnataka's government started the rioting.
Besides, the riots were never anti-government riots, like how it almost always is, in China. In this particular case, frenzied fans of the person who died began seeking the body as theirs, and not the family's, the family being seen as the enemy of the actor.
Here is an incident of rape in an orphanage in Bombay.
