I know i have seen more stories lately about innocent people being freed after newly analyzed DNA evidence. I think a good question is, how would we know if someone were wrongly convicted? What tells are there that the person the judge and lawyers said was guilty, that's now in prison, what could tell us they are innocent. Presumably there are tons of guilty people proclaim innocence every day to try to get out of their consequences. What separates them? There could be catastrophically high rates of innocent convictions and I'm not confident we would be aware of that
