I didn't notice it mentioned in this piece, but a different article on HN is suggesting she may have been homeless and was crossing where there was no crosswalk.
Homeless individuals frequently sleep under bridges, on the sides of off ramps and other infrastructure near highways. They are often walking where no pedestrian should be at all.
I would like to see the affordable housing crisis solved. Currently, there are only 30 affordable homes on the West Coast for every 100 poor families.* But it is entirely possible she did basically walk out in front of the car at a place where a driver had no reason to expect to see a pedestrian.
It would be nice if people would wait to see what evidence comes forth rather than jumping to conclusions about police conspiracies to hand wave away blame.
