“Being a gun-owner myself I believe people have the right to own guns and defend themselves or others if the extreme circumstance presents itself. However, in my opinion these “Make My Day” laws take defense a step too far. These law allow not only the ability to fatally shoot someone if you think they may threaten you, but they also let someone provoke a fight and still claim self-defense and they also allow you to fatally shoot someone to defend property. So if a shootout happens between two gun owners, whoever “wins” gets to claim self-defense. This is like a return to old spaghetti western movies. While I love those movies I don’t like the idea of them happening in real life.
So, where are all these “Make My Day” laws coming from?  Well, they start out being sponsored by Walmart and gun manufacturers to the American Legislative Exchange Council (ALEC). ALEC is a Koch brother’s (among others) sponsored conservative organization that creates boiler plate legislation to be pushed through state legislatures, in this case with the help of the National Rifle Association (NRA) [Source 1].
Why would Walmart want this legislation pushed through? Well, Walmart is one of the largest gun retailers in the United States and if guns that were sold in their stores are linked to non-justifiable homicide they are open to possible litigation and damages. How better to avoid this risk than expand what counts as justifiable homicide?
Conspiracy theories aside, the facts show that since the introduction of these instances of “justifiable” homicides have skyrocketed. In Florida alone the number of reported “Justifiable Homicides” jumped from 12 to 36 after the passing of their statute [Source 2]. That is a 300% increase! All of the other states with similar statutes have seen the same remarkable jumps in justifiable homicides. Whether these laws have actually lowered the instance of crime, will not be known until crime statistics get released for 2011.
So, there is a time and a place for defending yourself but our laws should not allow for people to shoot without thinking and have no repercussions. We live in a civilized modern society, please lets not revert back to the dusty streets of the cowboy westerns I so love watching.”

Think Progress is a liberal outfit, funded by Soros, so I’m going to have to look twice at those figures and see that they really are accurate, but the Walmart angle is interesting.
