Just because the CEO Ken Lay did (a lot of) unethical things does not mean business people are unethical as a group. Just because a former teacher did something unethical does not mean teachers are unethical as a group.
What concerns me is the people who see these examples as good evidence that the group is unethical as a whole. This ties in with "the part-whole fallacy" and "confirmation bias"...
