I live quite close by and it was so shocking and upsetting.
The families deserve to know what happened and for this not to be dragged out beyond what is necessary, as this will impact their grieving.
I would also like to know for sure what happened, because I've heard that it was a SUV involved, and that a normal car would not have been able to mount the kerb and crash through the fence and kill the children.
SUVs are a growing menace on the roads in areas where there is no practical need for them, but they are kicking out hugely increased pollution and present hugely increased danger. A child is 14 TIMES more likely to be killed if hit by a SUV than if hit by an ordinary car. Yet most people seem unaware of this. So yes, we do need to know what happened here, and no, not because we're ghouls, but because we want to reduce the risk of it happening again.
