The comments saying "she shouldn't have shown her anger." When someone throws out of second storey window and you don't show anger, you're basically giving them permission to go further. It's not like she told them what she thought of them randomly without provocation. She did it immediately after their misbehaviour. It's probably the only time she can say something and despite the threats, they did nothing to her because of the context.
You guys are funny. This is the same father who let his pre-teen daughter live or die in the streets. There's nothing he could do that's worse than what he's already done.
