"Research" is a word thrown around now a days that has an outcome predetermined such as so called "climate change."  Pope Francis is an advocate of that scheme which causes me to question his spiritual leadership.  He is in essence is saying God didn't know what He was doing when He created all life based on CO2 and O2.  If "greenhouse gases" are so dangerous to weather  and peoples' well being, why haven't they outlawed greenhouses? It's a con game, and they are using the word "research" to push it.

So what research have read that causes you to say CP doesn't deter capital crimes of murder?  If that is true, then imprisonment cannot deter criminal activity..
