Most situations like this are divisive, because there are probably multiple contributing factors behind it. If you have ever read the reports of disaster analysis teams or review boards, there tend to be multiple contributing events each from 1% to 50% of the problem (think of industrial disasters, riots, miscarriages of justice, anything). Everybody is raising their one or two valid concerns out of a bigger, full list.

I'm glad to see people getting upset at any kind of tragedy in the public eye. If there is anything, however small, that could be done to improve the world, let's discuss and make things happen, right!? The worst response would be "that's just life, how strange, oh well". That attitude keeps our species ignorant, complacent and passive, imo.
