He said what...?

"By calling attention to a 'well regulated militia,' the 'security' of the nation, and the right of each citizen 'to keep and bear arms,' our founding fathers recognized the essentially civilian nature of our economy. Although it is extremely unlikely that the fears of governmental tyranny which gave rise to the Second Amendment will ever be a major danger to our nation, the Amendment still remains an important declaration of our basic civilian-military relationships, in which every citizen must be ready to participate in the defense of this country. For that reason, I believe the Second Amendment will always be important."
JFK, April, 1960
