1. Innocent people do deserve to breathe. Innocent people have almost certainly died at the hands of the death penalty.
2. The government spends more money on the death penalty than on imprisoning people for life. That money could be spent on schools instead.
3. Some innocent people didn't blow their chance - the police and legal system blew their chance to convict the guilty person and instead convicted the wrong person.
4. Black people are far more likely to receive the death penalty. The colour of someone's skin shouldn't be a major determining factor in whether the government kills them or not.
