Phillip Bump reminds us that the Second Amendment "doesn't say a single thing about the right to own bullets":
Were the government to limit the amount of ammunition made and sold in the United States, there would still be an awful lot available. James Holmes bought 6,000 rounds online before his shooting spree in Aurora, Colorado. Bullets are so easy to come by that it's clear that huge stockpiles exist throughout the country. But unlike guns, bullets are single use. You fire a bullet, you expend its propellant. While attempts to remove guns from the streets would either be incalculably slow or require heavy-handed, dangerous government action, curbing the ability to buy ammunition would mean a natural diminishment of the arsenal that remains. Every time a bullet is fired, that bullet is lost forever.
Lexington compares America to Britain, where it is "very hard to get hold of ammunition":
Just before leaving Britain in the summer, I had lunch with a member of parliament whose constituency is plagued with gang violence and drug gangs. She told me of a shooting, and how it had not led to a death, because the gang had had to make its own bullets, which did not work well, and how this was very common, according to her local police commander.
Unlike in the United States, where the right to bear arms is guaranteed in the Constitution’s Second Amendment, Israel’s department of public security considers gun ownership a privilege, not a right. Gun owners in Israel are limited to owning one pistol, and must undergo extensive mental and physical tests before they can receive a weapon, and gun owners are limited to 50 rounds of ammunition per year.
