I want to know the answer to the following question:
In what year did Liebman announce his findings?
All the background I'm provided with is that "James Liebman, a professor of law at Columbia Law School, stated in 1996 that his study found that when habeas corpus petitions in death penalty cases were traced from conviction to completion of the case that there was "a 40 percent success rate in all capital cases from 1978 to 1995.". Is that enough to answer the question?
Answer: yes
