In real life, an unarmed woman is unlikely to be able to take on 6 violent thugs.

DING! DING! DING! we have a winner.
the whole point is, standing around watching it happen, she's gonna be left alone to face them. standing around puts her daughter FURTHER into harms way. cuz now, she's still there, the kid is still there, husband is out of the picture, and there's 6 thugs that could choose to come after her.
help or scram.
and also, yes. a set of parents enraged for having their daughter assaulted in front of them stand a very good chance of taking out 6 guys, or at least putting them to flight.

That’s the thing if people joined in to stop these thugs then it would have been portrayed by the media as a bunch of whites trying to attack 6 impoverished youths who didn’t know any better because life has been “hard” for them.
