How about suing the person that actually killed her. This is embarrassing.

Taking money from the kids because the “school” has funding and isn’t a “person “

I’ll say it - Catherine would be ashamed.

I've seen something similar before at a private event where someone got seriously injured and the organizers tried to blame the instructor they hired (who happened to be a non-native English speaker from a foreign country who couldn't possibly know the ins and outs of the venue or American culture) rather than fix the glaring safety omissions they made. I think this is the right move. Organizers do have a responsibility to try to sort out potential safety issues at events they host. It's a type of due diligence.

Organizers shouldn’t be responsible for someone mistaking an accelerator for the brake pedal and the resulting actions of that mistake. If it was event related, sure I could understand, but using the parking lot in a similar manner as school loading/unloading introduced the same risk levels that normally exists. They can’t be responsible for someone else’s unintentional gross mistake that was under that persons control (that could have occurred in any situation, not event specific).

Please don’t set a precedent of suing our schools just because they “have money”

Doesn't this fall under "the assumption of risk" doctrine?

It sounds like the driver is (accidentally) negligent.
