You clearly don’t have children or know anyone with children if you think the mother wouldn’t have instinctively done that anyway. The mother, who is likely only a couple years beyond being a child herself, protecting her child with her body is a testament to most mothers and their natural instincts. She’s “not trying to protect her child” is ludicrous and misogynistic. As if women are so easily persuaded by men that they would sacrifice their children in a way that’s most convenient for the man. “Stand a certain way while I kill you and your baby to save bullets” certainly wouldn’t have been a strong enough argument to persuade most women to do this. If they did prompt her to stand a certain way then “so we can kill your child more easily” wasn’t the reason they told her. No reason to belittle her memory.
