I mean without knowing more information than "she was being attacked by an ex boyfriend in a domestic violence situation" she very well could have been. I don't fault her at all for wanting to call the cops. 100% of the fault lies with the responding officers and the system that allows them to operate with the training and mindset that they have.
So it wasn't just UV A or B which is found in normal sunlight, but the extremely dangerous and potentially cancer causing UVC radiation that your body does not have a natural resistance to and most sunscreen does not protect against either.
Monumentally stupid.
