One thing Navegator got right is that the antiquated laws have not changed. In most cases the Judge and the 2 lawyers decide the outcome. Juries are still rare. Court rooms can be closed to the public. When you see the photos of a drug dealer beside his huge stash do not for a moment think he is going straight to jail. The judge will often let them go due to a lack of evidence. Municipal police will not arrest a robber unless they see him committing the robbery. Most crimes do not result in a court case. Justice in Mexico was supposed to change but it remains hopeless. However I find it hard to believe that someone was handcuffed to a light post. There is more to this story.
