This is why I hate reading statistics in the paper. Am I the only one who thinks that this was written to "prove" that the death penalty doesn't have a deterrent effect? As if you could set up a hypothesis that goes "Say it had a deterrent effect; then, in the places where they have it, you should see lower rates of homicide. If you don't see that, there's no deterrent!"
What lousy logic! It sounds like the Chewbacca Defense!
I'm no fan of capital punishment, but this is just bad pseudo-science. I can't believe somone got funding for that study.
