I agree that going back in and getting another gun was excessive. I think most people on here agree that crime is rampant as of late, urged on by the down economy. Now I would personally never do something like what he did, but in a way I see it as a message that is sent to criminals, we are tired of you robbing, raping, and killing us. If you try and rob someone, you have a chance of not getting away alive. That is the message that needs to be sent to criminals. If the law allowed for such force used when in a self defense situation, I can't help but wonder what affect that would have on crime rates. Most criminals just have a gun for looks, to scare people to give them what they want, a lot don't even use it, they want something quick and easy without a fight and run from fights. If every time one of their buddies was shot like this in a robbery, I think they would start saying this is to risky, time to work for micky d's.
You can also look at it this way, the kid was 16 and already on the career criminal path unless something major happened in this kids life. Now I believe in second chances, but by this kids death, how many lives are saved down the road? We will never know, but if at 16 the kid was already robbing stores with a gun, what is he going to be into when he turns 20 or 30? How many people would he have killed in robberies and possible gang activity? As morbid as it sounds, the pharmacist could possible have saved lives down the road by killing the criminal and is going to prison for it. Like I said I would not do it, but I can't blame him for doing it either. Criminals show no mercy for us, why should we for them?
