Justice Undone in the Dorothy Stang Case

This just infuriates me:

On Tuesday, after a two-day trial, a jury in Belém, in Pará State, acquitted the man, Vitalmiro Bastos de Moura, of conspiracy in the murder of Sister Dorothy Stang in February 2005.
The trial was the second in which a jury had considered Mr. Moura’s role in the killing. He was convicted and sentenced in May last year to 30 years in prison on charges of ordering the killing of Sister Dorothy, 73, who was a staunch advocate of protecting the rain forest.
Under Brazilian law, a retrial is required for first offenders who are sentenced to more than 20 years. This time, the jury voted 5 to 2 to accept the defense contentions that Mr. Moura had no motive to be involved in Sister Dorothy’s killing and that it had been carried out solely by Rayfran das Neves Sales, who confessed to shooting her and is serving a 28-year sentence.

I'm sorry, but no. Para, where Stang was killed, is notorious for corruption and the landed elite doing pretty much anything they want to, be it illegal logging, graft with politicians (who are also from the landed elite), and even intimidating and killing people who try to save the environment and fight for the rights of the poor. And there is just no way, who is already serving time for her murder, and who was a poor worker in the area, decided to just shoot Stang without any goading or payoff from anybody, particularly given that, this time, he just magically changed his entire story and said it wasn't Moura's gun and that nobody paid him off. No way. Not in this case, and not in just about any land-struggle case in Para. Tom Stang, Dorothy's brother, is dead on:“That guy [Sales]was offered up as a sacrificial lamb. But the darker forces that created him have been allowed to go free.” This is just terrible news in a case that should have seen fuller justice for an important voice in the land-rights and conservation struggles in Brazil.
