Justipedia explains Second Amendment
The Second Amendment is one of a number of amendments to the U.S. Constitution that grants citizens certain freedoms. The Second Amendment, although it grants citizens the right to keep and bear arms, does not necessarily mean that any citizen of legal age can keep and bear any type of firearm or weapon. In fact, there have been many legal disputes about such issues over the years. The Constitution was written before the time that weapons such as nuclear bombs were invented. So, the government deals with questions regarding the exact types of weapons that are legal and illegal.
