Jennifer Givens, director of the Innocence Project at UVA’s School of Law, said research suggests that the “error rate” in capital cases nationally is more than 4%. That means, she said, that at least 100 of the 2,500 death row inmates across the country are actually innocent. “If we want to eliminate the risk of executing innocent people, the only way to do that is to pass this bill,” Givens said.
