An excerpt from former Supreme Court Justice John Paul Stevens' 2014 book, "Six Amendments: How And Why We Should Change The Constitution," in which he explains the five extra words that can fix the Second Amendment...
As a result of the rulings in Heller and McDonald, the Second Amendment, which was adopted to protect the states from federal interference with their power to ensure that their militias were “well regulated,” has given federal judges the ultimate power to determine the validity of state regulations of both civilian and militia-related uses of arms. That anomalous result can be avoided by adding five words to the text of the Second Amendment to make it unambiguously conform to the original intent of its draftsmen. As so amended, it would read:Read Stevens' full piece here.
“A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms when serving in the Militia shall not be infringed.”
Emotional claims that the right to possess deadly weapons is so important that it is protected by the federal Constitution distort intelligent debate about the wisdom of particular aspects of proposed legislation designed to minimize the slaughter caused by the prevalence of guns in private hands. Those emotional arguments would be nullified by the adoption of my proposed amendment. The amendment certainly would not silence the powerful voice of the gun lobby; it would merely eliminate its ability to advance one mistaken argument.
