I'm sorry they were arrested. Every time I get one of those fraudulent e-mails, it reinforces my belief in the force of human cupidity and in entrepreneurship. Barnum was right--There IS a sucker born every minute. If they were not greedy, they would not be taken in.
By the way, I report every one of them to the appropriate authorities. I recently received one which looked legit and, when I asked for a phone number and an American bank reference in New York, they got very upset with me, accusing me of a lack of trust.
