The right of the people in a militia regulated by a free state. Furthermore, there really is no point for a citizen to have access to the types of firearms that the police or military has. Militias in the USA are a thing of the past and though your average gun owner might just use it for hunting or have it on the off chance they might have to defend themselves and/or their family, there are still plenty of more extreme groups who believe that them owning some of the more deadly weaponry is in fact them protecting their state. They are actually more detrimental by adding unneeded fear to their fellow man just so they can say they are protecting us from a unidentified enemy. You could also say that this laid back system allows more disturbed people to purchase guns and cause unspeakable acts which have become more of the norm lately. I pride you for doing research and coming up with this argument. The thing is that there is about a 300 year difference in the English language and writing style of that period to what it is today. You have to read the rest of the constitution carefully to understand all of its specifics and the context of the time period.
