how people will react on a dog being bitten on the street

Two guys put a toy dog in a bag and pretended that they are beating the dog. They pre-recorded the dog barking and turned it on  at the moment of attacking a soft toy
So what do you think? People expressed sympathy or tried to help the dog?

Unfortunately, the vast majority of people quietly passed, silently watching or even helping to beat the dog.
