By contrast the example of Harris County convinces me that law enforcement prosecutes a lot of shaky cases that they know wouldn't hold up. See https://www.texastribune.org/2017/03/07/report/ https://www.texastribune.org/2017/03/07/report/ for how there is only one county in the country that actually double checks drug tests after someone has plead guilty. The result is that the one county alone manages to exonerate more people each year than the next three states combined. There is no reason that I know of to believe that Harris County has an abnormal number of people wrongfully convicted. They are only unusual in figuring that out and turning them free later.
