These two posts pretty much explain the situation:
This is also why socialism/communism doesn't work."A common explanation of this phenomenon is that, with others present, observers all assume that someone else is going to intervene and so they each individually refrain from doing so.

People may also assume that other bystanders may be more qualified to help, such as being a doctor or police officer, and their intervention would thus be unneeded."
