Title:
Capital_punishment_in_the_United_States

Context:
Puerto Rico's constitution expressly forbids capital punishment, stating "The death penalty shall not exist", setting it apart from all U.S. states and territories other than Michigan, which also has a constitutional prohibition (eleven other states and the District of Columbia have abolished capital punishment through statutory law).

Question:
How many US states have passed laws outlawing the death penalty?
