Okay kiddo, let me explain Hudson v. Craft to you like you're five!
Hudson v. Craft was a case that went all the way up to the Supreme Court of the United States! A "case" is like a big fight between two people or groups, and the Supreme Court is where really important fights get decided.
Now, in this case, Hudson was a guy who had been arrested by police officers. He said that when he was arrested, the officers used too much force and hurt him. He wanted to sue the officers for hurting him.
But here's the tricky part - before you can sue somebody for hurting you, you have to follow some special rules. One of those rules is that you have to "exhaust your remedies." That means you have to try to fix the problem using all the tools that are available to you before you go to court.
One of the tools available to Hudson was to file a complaint with the police department. But he never did that. Instead, he went straight to court.
The question in this case was whether the "exhaust your remedies" rule applied to Hudson's case. In other words, did he have to file a complaint with the police department before he could sue the officers who hurt him?
The Supreme Court said yes, he did. Even though the rule was kind of confusing and hard to understand, they decided it was really important to follow it in this case.
So, to summarize, Hudson v. Craft was a big fight between a guy who was arrested and the police officers who arrested him. The guy said the officers hurt him and he wanted to sue them, but the Supreme Court said he had to follow a special rule before he could do that.
