The death penalty is an unwieldy weapon, used too often against vulnerable communities so the government doesn't have to address the underlying social factors at hand (such as institutional poverty, racism, corruption in the police, etc). All too often, convictions and executions are discovered too late to have been overturned by new evidence, after an innocent person has been murdered by the state. To wield such an unreliable tool against the public in some sort of ill-thought-out revenge by the state is a huge red flag. Are we a dictatorship or a leader of the free world? A civilized nation does not have to resort to murder to protect its servants.
