This reminds me of a dentist who was a witness for the prosecution, who lied to the jury and basically said bite marks were as good as finger prints (they aren't, the most you can say is that they're similar). Defendant Ray Krone ended up going to prison for 10 years, including two on death row, on just that evidence when NOTHING else from the case matched him (the jury was also filled with morons apparently). He wasn't released until DNA evidence cleared him. Yet in the very end, that dentist, Raymond Rawson who went on to become a senator, refused to admit he made a mistake and had no issues keeping an innocent man in jail to not tarnish his own reputation and to fulfill his own ambitions.
The American justice system is anything but at times. To Ray Krones credit, he now works for Witness to Innocence and works to abolish the death penalty as he almost was executed himself despite his innocence.
I tell you, though, as much as I love Forensic Files when they capture the criminal, there are some episodes that make me realize that there is a ton of corruption in our courts.
