If you want to look at what our society will be without guns, look to prison, a place with some of the highest security available, yet people still kill on the inside. Even to say you get rid of all guns, used/possessed by 'good' and 'bad' people, those who have it in them to do harm to others, they will. In the place where it should be most apparent to someone that what they are doing is bad, and they still sharpen that shank, make that club and use it!!
If I am to provide a personal opinion, being of the younger consensus in this forum (20) and growing up in this "generation 'Rx'" kind of world, i see it is the exact lack of firearm presence which contributes to the lethal use of them today. Kids should be taught about firearms when they are young, their minds are malleable and they begin with a foundation that guns are not toys, but useful tools; for both sport and protection of property and nation. It is when a persons first experience with a firearm is through the screen of a tv, the trigger of a controller, that they develop into the alternate belief that it is a game, with no real world repercussion. And with many adolescents, that is restricted by parents, educators, and the general moral fabric of this country, but some will always slip through the seams. How is it the trend, that 50 years ago, my uncle was able to bring a 30-06 to school and sell it to a friend, and not a eyebrow was raised, but in this day and age, we have metal detectors checking people for concealed weapons, and this is such a common incident.
I leave with this, for those who say that society isn't playing a role in this, and that it is all the gault of guns,remember this:
In Call of Duty: Modern Warfare Two, (a game which an incredible number of minors and adults play, there is a level called 'No Russian,' The 'mission' begins disembarking an elevator in an airport, with automatic weapons with the objective being to kill as many civilians as possible and send a message to whatever fictional government the developers created.
Once someone has the disposition to commit an act so horrid, they will resort to whatever means available to fulfill it.
