I want to know the answer to the following question:
Between 1973 and 2015, how amny prisoners were acquitted or received pardons or commutations of their death sentences due to possible innocence?
All the background I'm provided with is that "In total, 156 prisoners have been either acquitted, or received pardons or commutations on the basis of possible innocence, between 1973 to 2015.". Is that enough to answer the question?
Answer: yes
