Okay, kiddo, let me try to explain what an indictment is in very simple terms.
Imagine you and your friend are playing a game of tag at school. Suddenly, your friend tags you so hard that you fall down and get hurt. You feel really angry with your friend and you want them to say sorry for hurting you.
In real life, when someone does something against the law, they can also hurt other people. The police investigate and collect evidence to find out who did something wrong. Then, they take that evidence to a special group of people called a "grand jury".
The grand jury is like a group of grown-ups who listen to the evidence that the police have collected. They talk about what happened, and they decide if there is enough proof to say that someone probably broke the law.
If the grand jury says that there is enough evidence, then they write up a special paper called an "indictment". The indictment is like a list of accusations, or charges, against the person who might have broken the law.
So, an indictment is like a way to say, "Hey, you did something bad and we have proof. Now you have to come to court and explain yourself."
Does that make sense, little one?
