In July 1999, around a 10th of the black population in the Texas town of Tulia was arrested on drug charges. The only evidence was the word of an undercover agent. That was enough for many of the defendants to be convicted and sentenced to long prison terms. The case brought Tulia to national attention and led to accusations of racial bias in America鈥檚 war on drugs.
