The Second Amendment guarantees your right to keep and bear arms. This means you have the right to have a gun for your own protection and for hunting and other purposes.
The Fourth Amendment protects you from unreasonable searches and seizures. This means the police can't search you or your property without a good reason, and they can't take your things unless they have a warrant.
The Eighth Amendment prohibits excessive bail, excessive fines, and cruel and unusual punishment. This means you have to be able to afford bail if you're accused of a crime, you can't be fined more money than you can afford to pay, and the government can't punish you in a way that's too harsh or unusual.
