Moral police is like when someone decides how other people should behave and punishes them if they don't behave the way they think is right. It's like when your mom tells you not to do something because it's bad for you, but imagine if your mom was telling everyone in the world what they should and shouldn't do. Sometimes people think they have to be in charge of everyone else's behavior and they might judge or get angry if others don't do what they think is good or right. But it's important to remember that everyone has different beliefs and values, and it's not up to one person to decide what's right for everyone.
