That's literally my only problem with the death penalty nowadays. We have DNA so we are able to avoid executing the innocent now. My problem with it is it is way too expensive to do lethal injection and these fucks don't deserve it. I am firm believer that the killer should receive the exact same type of death they inflicted. If you killed someone by lighting them on fire, guess what - I think they deserve to know exactly what the person they killed felt. It's disgusting we treat these fucking criminals like a pet that we loved dearly.
