Well, the 2nd Amendment reads as . . . So the "well regulated" part isn't about regulating the right to bear arms, but maintaining a strong militia. Where people get upset about gun regulation is the part that says "the right of the people to keep and bear arms shall not be infringed." Many people see any laws that dictate what we can and can't do with firearms as exactly that, infringing. The whole issue is very difficult as you can no doubt guess. The brevity of the amendment has left it up for a hot, contentious debate for pretty much the whole history of the nation. Wikipedia actually has a great breakdown on the issue.A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.
