Turn state's evidence

Ok sweetie, sometimes when people do something wrong or against the law, the police or the government want to find out who else was involved. So they talk to the people who did the wrong thing and ask them questions.

If someone who did something wrong decides to help the police or the government by giving them important information about the other people involved, this is called "turning state's evidence".

Imagine you and your friends did something wrong and the police came to ask you questions. If you decided to tell them everything you knew about what your friends did, you would be turning state's evidence. The police might then use the information you gave them to find out what really happened and hold the other people responsible for doing something wrong.

People might choose to turn state's evidence for different reasons, but usually it's because they want to help the police or the government get the whole truth and make things right. Does that make sense, sweetie?
