Read the excerpts from "Wrongful Convictions” by Jon Gould and Just Mercy by Bryan Stevenson.

"Wrongful Convictions”

Now, with DNA evidence available, it is essential that that testing be done earlier in a case because certain people can be weeded out from the beginning. And I recognize that that testing is expensive, but the testing is likely going to be used anyhow in these cases, so you might as well do it earlier.

Just Mercy

We also make terrible mistakes. Scores of innocent people have been exonerated [cleared] after being sentenced to death and nearly executed. Hundreds more have been released after being proved innocent of noncapital crimes through DNA testing. Presumptions of guilt, poverty, racial bias, and a host of other social, structural, and political dynamics have created a system that is defined by error, a system in which thousands of innocent people now suffer in prison.
