There are more cases of subtler failures that are smaller in scope, eg. in the Chicago metro[1], or on the UNC campus[2].
I do agree with part of your sentiment. Those two examples are the worst case scenarios where misfortunes happened to align, and there are periods in history, as well as other countries today, where this sort of problem was/is rampant.
This is also not (exactly) a recent problem - the groundwork, no pun intended, was often laid long ago.
