I haven't done the research, so I do not have the information necessary to present a well-supported argument.
Nevertheless, I'll venture some reasoning (in other words, part of an argument).
Conclusion: Guns should be banned.
...A gun is a weapon. For all intents and purposes, it is designed to inflict harm, whether it be upon a human or an animal. Even if a gun is being used in self-defense, the fact of the matter is that it's being used to hurt another person. There is scarcely a good reason for permitting gun ownership for those working outside of the executive branch of government. Some may argue that every person has a right to defend his or her life and property. First, burglary does not warrant lethal force. Beyond that, how common is murder? Certainly not commonplace enough to justify placing guns in the hands of untrained civilians. Rather than arming themselves as though they were a self-contained military outfit, families should invest in home security systems. Not only would this serve to deter potential thieves and those looking to commit other heinous acts, but it would also alert trained professionals in the event that such criminals are foolish enough to disregard the precautions. The bottom line is that guns do not belong in the hands of unauthorized persons, even if such people have the best of intentions.
Conclusion: Guns should be permitted with reasonable restrictions in place.
...Prohibition is a tired game. Sure, it works if the product in question is military-grade or otherwise difficult to find, but neither of these stipulations applies to a standard firearm. That being the case, prohibition would do more harm than good with respect to guns. People with the necessary resources would find a way to get their hands on them, while average people looking to protect their families and property would be left vulnerable. It does not stop there, either. There is no doubt that organized crime groups would capitalize on such government restrictions. Such a probability would serve to further fan the flames of violence. At the end of the day, people need to come to terms with the fact that the police are by and large an after-the-fact solution. People need a means to defend themselves when no one else can or will. Concerns about such people being unequipped to handle firearms are misplaced. Few people will advocate gun ownership in the absence of appropriate licensure. Therefore, given licensing necessities and restrictions on what types of firearms can be owned, there is no good reason why citizens should be barred from capable self-defense in the form of gun ownership.
I did my best to argue each side to a reasonable extent. Without doing further research, I cannot say that I necessarily support one side or the other.
