Why didnt pernell whitaker get disqualified for the low blow extravaganza against j.c.chavez?

if it were a foreign fighter hitting an american fighter with that many lowblows he the foreign fighter gets dqued automaticly...but americans get away with murder and corrupt refs shine it on...watch this vid where in the 6th round chavez is givin 5 minutes to regenerate after getting hit in the eggs only for whitaker to hit chavez again in the eggs after the recoop..in rounds 6 & 7 chavez got hit in the eggs 6 times and the biased joe cortez never even took a point away when obviously whitaker shouldve been dqued..watch the full 6th & 7th rounds and ask yourself why didnt whitaker get dqued a href="http://www.youtube.com/watch?v=4ohTGhwDbw0" rel="nofollow"http://www.youtube.com/watch?v=4ohTGhwDb…/a
