I think that's kind of a naive take.
I think its a fair thought in a perfect world where she could have just said "you must be mistaken" and know she won't get shot just for talking back.
Imagine you're going about your day doing normal stuff, and suddenly you have 4 (5?) armed thugs running at you with guns drawn and a long history of shooting people for fun and getting away with it.
Anyone is gonna be panicked, anyone is going to take a split second to try and decide where their best chances of survival are. Especially with a baby in the car, I can't blame her at all for trying to get away from the situation, regardless of whether she stole fucking diapers or not.
They could have shot her and her baby if she had just stopped and got out too. She made a choice and it ended in tragedy, but it's nowhere near her fault.
