Take Cameron Todd Willingham, executed in Texas in 2004 for killing his children in a house fire. Years later, leading fire experts concluded that fire was accidental. The state executed an innocent man. That's the risk baked into your approach: every execution depends on the system being perfect, and it never is. Repeat offenders are dangerous, yes, but their past crimes don't prove they'll reoffend, and life without parole already keeps us safe. El Salvador's crackdown also produced plenty of wrongful convictions, no matter how much safer it feels. Execution just makes our mistakes irreversible.
