When it was first drafted, the idea is to have a universal militia during the 1790's because it is very expensive for the government to bring guns to all of the members of the militia. They say that this right originated from the English courts where the king requires his subjects to bear firearms for military duty. During that time, they don't have a regular army and police force so certain men had to keep watch and ward at night to keep the peace in the communities, hence the need to keep an assault rifle in the house of certain men. These men are tasked to ward off bandits and to capture and confront suspicious persons.
The only difference is, the 2nd Amendment does not discriminate against social classes unlike with the English where only the wealthy are able to bear arms. It should also be emphasized that in arming the militia, which is a natural defense of any free country against invasions, or any uprising that will jeopardize the peace and democracy in a country, the right against usurpation and arbitrary power of rulers within or outside the country can be impede and eventually discouraged. Some historians and philosophers say and believe that injustice in a country will be exerted unless forcibly resisted. Having the right to bear arms gives the ammunition to make sure that injustice does not happen - figuratively and literally speaking.
With the advancement in technological warfare, the classes of guns supported by the 2nd amendment have also grown in number. It includes ak47 and m16 riffles. The registration process has also improved with all the requirements necessary for a person to acquire a gun. There are also individuals who are prohibited from carrying a gun because the court does not see them fit to carry a weapon that may cause harm to a multitude of people.
Even if the 2nd Amendment was created to further the rights and liberty of the people, it can also very easily cause the violation of the rights of people facing the other end of the barrel. Despite this possibility, the 2nd Amendment has done more good than harm to the people and the state. There are enough regulations to keep it and its consequences in check. All in all, it has promoted liberty and uphold the rights of the people.
