Herbert probably doesn't realize it, but the major Texas media outlets would harbor no compunction about exposing racism in Tulia -- if it existed. If this story happened as described, the Dallas/Ft. Worth, Houston and Austin media outlets would be covering it like white on rice. Not to mention the Amarillo and Lubbock media.
Yet, after three years, this is the very first I've heard about the affair.
So, I'd like to see some corroboration before I buy into Herbert's allegations. Indeed, I wonder if Herbert himself has any corroborative material...
Federal Prisons are full of folks of all colors doing serious time for drug conspiracy in which no drugs were found. The NYT is only running with this for the race effect and because it's Texas and not Massachusetts. I wouldn't wager my life on Herbert's veracity.
