This is a sad situation, but he brought it on himself. What surprises me (OK Maybe not) is he said "he did it because he borrowed some money from somebody to fish the event and felt pressure to repay them" OK so if I understand right, this guy is not a poor up and coming pro, it says he and his partners have torn up the south CA tournaments, meaning he was wining. So he obviously had other financial issues that he couldn't get the entry fee and costs together so borrowed the $$.
If you can't aford to gamble, don't - period. I know its a hard concept, but no sympathy from this side for him, don't go in debt for a sport, even if you are on the pro level, as nothing is guaranteed in life.
We had our share, i think it was last year a father-son team was caught keeping fish in a box under a dock and loading it up for tournament weigh-ins, terrible thing to teach a kid and he had his kid doing it with him!
