Is there higher crime and murder rates in northern or southern states? Is there higher crime and murder rates in cities where Democrats or Republicans have been in control? Is there higher crime and murder rates in cities with large minority populations? Large illegal alien populations? How many mass shootings have occurred in gun-free zones vs places where guns may be lawfully carried?
Can answering these questions identify where the higher murder rates occur that you claim exist within this country? Are there a lower murder rates in countries where individual liberty is curtailed?
You ask one question to arrive at a predetermined answer. I ask many questions to find out what the answers are.
