The police in England and Wales have a lot of power to keep people safe and make sure laws are followed. They can do things like arrest people who break laws, stop and search people if they think they might have something illegal, and ask questions to help solve crimes.
They have to follow rules and laws themselves though, and can only use their powers in specific situations. For example, they can only stop and search someone if they have a good reason to believe they might be carrying something illegal, like a weapon or drugs.
It's also important to know that police officers are not allowed to use their power to be mean or unfair to people. They have to treat everyone with respect and should only use their power if they really need to.
That's why it's important to trust the police and know that they are there to help us stay safe and secure. Remember, if you ever have any questions or concerns about the police or their actions, it's important to talk to a trusted adult or seek professional advice.
