Traffic lights encourage drivers to move quickly, and ignore their surroundings. They tell drivers to trust the intersection to be clear if the signal is green. This means that if a prudent and cautious driver makes the single mistake of misreading the light, it risks a high speed colission.

A 4-way stop would have slowed traffic, likely preventing fatalities in this case. Even if the driver missed the stop sign, the cross traffic would be slow enough to not push the SUV into the corner of the intersection. At the same time there wouldn't be pedestrians in the corner, because 4-way stops allow pedestrians to cross quickly, and doesn't require them to wait directly next to intersections.

This is an urban road. It was a choice to prioritize traffic speed and car throughput over pedestrian safety. This is the inevitable result.

The intersection requires pedestrians to wait, unprotected, in a dangerous location directly at the corner. The designer of the intersection recklessly endangered people to the most serious degree and is being let off scott free.

The vehicle that did the killing was an SUV. SUVs are large and heavy, with high blunt front ends. These are incredibly dangerous in a colission, far more likely to cause fatalities than modern passenger cars with a low nose that scoop under pedestrians in a colission. The car's designer, manufacturer, and vehicle regulator who allowed this dangerous design onto the streets recklessly endangered people to the most serious degree and are being let off scott free.

This court isn't even able to try most of those responsible.
