I for one am done with the "few bad apples" apologia. If they were truly a few bad apples, rather than evidence of an entire institutional mindset, then their fellows would not always close ranks around them like they do. They would see to it that these bad apples are brought to justice because a) that's the right thing to do, and b) to protect the legitimacy and reputation of their institution.
But they don't, so....draw of that what conclusion you will.
