How Many Are Wrongfully Convicted?

We know that African-American men make up a disproportionate percentage of the federal and state penitentiary populations, but how many of those men are there because they have been wrongfully convicted?

According to the Innocence Project"s "200 Exonerated: Too Many Wrongfully Convicted",

"We...know that those who are exonerated by DNA are a subset within a subset—a fraction of cases that have evidence that still exists and can yield DNA results, within the tiny fraction of cases that even have DNA evidence as part of the crime. 

Very few cases involve physical evidence that could be subjected to DNA
testing (for example, it is estimated that, even among murders, only 10% of cases
have such evidence)."

Also, according to Innocence Project data, here is the figure that no one should be shocked about: 146 of the 245 people who have been cleared using DNA evidence are African-American.
"Seventy percent of the 245 people who were wrongly convicted are people of color. Sixty percent were African-American. By now, everyone knows that African-Americans are over-incarcerated. The prison population is 40 to 45 percent African-American, which is wildly disproportionate, but the percentage of those exonerated is even higher," said Ferrero
