> maybe if she'd had a gun she wouldn't have been shot

And how do you imagine that, exactly? You think that cop was fine shooting her for driving away in panic, but would patiently wait for her to grab a gun? And what would you like a person in her situation to do with the gun? Shoot him? The fact is, pulling a weapon in front of a US cop is begging to be killed on the spot. A common point of advice is that if you're stopped in the US by police, you should never look like you're reaching for anything, because the worst-case penalty for that is death. It instantly escalates the situation to life-or-death for a group of people that is largely already itching to pull the trigger.
