While I agree that convictions in Texas are based on the evidence just as they are everywhere else, the evidence presented in Texas may not be the same as it would be if the trial were to take place elsewhere.
As of May 2010 the state of Texas is responsible for having 41 convictions overturned on DNA evidence out of 254 nationally (16%.) They notoriously allowed evidence of arson to be used that would have been inadmissable at trial almost everywhere else in the country and failed to reverse the conviction of the defendant who was put to death even after the invalidity of the evidence and the lack of a crime was exposed. They have executed the retarded.
They spend approximately $200 million annually for a public defenders’ office that handled 470,000 requests in 2010. That is $425 per defendant.
When it comes to murder plots, it seems to me that deals to co-defendants, based on testimony against other defendants should be illegal. Does it make sense to tell someone you suspect is guilty of murder that you will give him a lesser sentence only if he testifies against someone else? Does the phrase “no honor among thieves” ring a bell? I suspect it is true for murderers as well.
The facts as asserted in Wikipedia certainly make this woman sound guilty, but the history of Texas and the death penalty call for a thorough investigation of every conviction and a moratorium until it is completed.
