If for no other reason, because we want one. Quite honestly most everybody in this world including many who are flat broke induldge on things they don't need simply because we want them. AMERICA was founded as a free society to do as we please so long as it was within limits. So if one feels like going out and shooting 30 cans in a row, why shouldn't one be allowed. It would be like saying that you can't have more than 1 child, 1 car per person, or you should only be allowed a daily ration of gruel. We all have our guilty pleasures that we induldge in, some choose cars, some choose boats, others choose stamps, some choose guns, and so on. How is it anybody elses business what somebody else chooses to do with there time, and what they choose to buy. And how will limiting people to a single shot gun help stop crime? Look at areas where guns are outlawed, they just happen to be some of the most dangerous places next to warzones, coincedence.
I truely feel bad for the children, and would hate to think of going through this with my own son now that I'm a father, but on the other hand this crime could have been committed with a baseball bat, knives, machettes, axes, car, or anything else that somebodies twisted mind can misuse. When will we as a society come to realize that it isn't the weapon but the individual that is the problem? If somebody was twisted enough, they could use a stuffed bunny rabbit with a brick in it, but I doubt we wil lever hear for the banning of stuffed toys and houses to prevent a tragedy like that from happening.
And I know this should be in the politics section, but in all honesty I feel a large portion of the blame lies with our society as a whole as we have devalued human life. People have now become desensitized to violence courtesy of TV, abortions are just a thing anymore and many feel it should be allowed to be done to children right up until birth(yes I call them children as it is a life at conception), and not to mention video games and the message that has been sent of how killing is just good entertainment. And before it is said, no I'm not calling for the banning of video games or more restrictions on them. What I AM calling for is people to be responsible for there actions, to accept responsibity for there actions, and for people to realize there are some people in this world who have issues that are beyond the grasp of normal thinking. And that those kinds of people will do harm to others no matter what they have to go through to do it.
I'll stop there before I go off the deep end and bring religion into it.
