Liars and "justice for all"

Saw this on local news, probably the search terms are "Ricky Jackson" + <something about justice> According to: https://www.themarshallproject.org/2014/11/21/the-corrections

In Ohio, Ricky Jackson and Wiley Bridgeman were freed hours ago, 39 years after they were wrongfully convicted of murder – during the Ford administration.

...

because the principal witness against them, a boy of 12 at the time, now says he lied when he identified Jackson, Bridgeman, and a third man as murderers. “Everything was a lie,” said the witness, Eddie Vernon. “They were all lies.”
