Well, do you know what rules are? They are like instructions that we follow to do the right thing. Now, in some places, people follow different rules based on their own religion or beliefs. In Germany, there are people who follow Islamic rules called Shariah.
But sometimes, some people try to make others follow these rules, even if they don't want to. This is not allowed, and it's called forcing others. In the city of Wuppertal in Germany, some people who follow Shariah tried to force others to follow it too.
They called themselves "Shariah police" and dressed up in special vests to make them look like the real police. But they were not the real police, and they did not have the permission to make others follow Shariah rules.
This was very wrong, and the real police in Germany did not allow it. They said that everyone should be free to follow their own religion or beliefs without anyone forcing them to do something they don't want to do.
