How does the Supreme Court interpret Second Amendment gun rights?

The Supreme Court is like a teacher who decides how fair the rules are for playing a game, in this case, the game is about gun rights, and the rules come from the Second Amendment.

Imagine you have a rulebook that says "You can bring your toy sword to school." But sometimes, teachers say, “What does ‘toy sword’ really mean? Is it a little plastic one or a big real sword?” That’s like how the Supreme Court looks at the Second Amendment, which says "The right of the people to keep and bear Arms shall not be infringed."

Sometimes they think it means you can carry a gun anywhere, like having a toy sword in your backpack. Other times, they say it depends on where you are, like if you're in a school or a restaurant.

If someone says the rule is too strict (like saying you can't bring a big sword to school), the Supreme Court will look at how the rule was written and what people meant back then. They might say, “Yes, you can carry your sword, but not in the library!” That’s like giving a warning or changing the rules so everyone agrees.
