Forensic Commission, What's the purpose?

I agree with the Austin American Statesman Lawmakers should reassess panel's purpose editorial about the importance and most of all potential of the Texas Forensic Science Commission, and hopefully they will figure out and/or alter there purpose while they are on OUR payroll. I am not sure how much taxpayer money it cost to employ the nine members of the Texas Forensic Science Commission, but more importantly, I don't understand their purpose, and neither do they apparently! It's obviously up to the courts to prove a criminal case, and if it's a capital case, whose punishment has been rendered, then isn't it too late to overturn the case or appeal? As with the case of Cameron Todd Willingham, who was sentenced to death and executed in 2004 for a fire in his home in 1991 that killed his 3 children, they were not able to draw a conclusion using forensics until he was already executed, at which time the report concluded that nobody could have used the available evidence to show that Willingham set the fire. If the purpose of the commission and report is to help prevent improperly charged individuals, then it is important to remember that the evidence gathered by commission appointed experts is not offered as evidence in a court of law. Maybe the purpose should be to prove that evidence is presentable and viable before being used and before the court precedings start, especially with capital cases. It doesn't seem that the commission is doing its job, whatever that may be, furthermore, with the recently released Willingham report, I find it alarming that 4 of the 9 members have been suddenly replaced by Governor Perry. Either way, mabye lawmakers will soon figure out what they've created, because it is pretty apparent that they may have a huge responsibility that was not originally intended.
