Why Do Governments Secretly Spy on Their Own People?

Imagine you're in a classroom, and the teacher keeps an eye on everyone, even the ones who are quiet or well-behaved. That’s like government surveillance. Governments sometimes watch people they know without telling them, just to keep things safe or find out secrets. They use tools like cameras, phones, and computers to see what people do, say, or write. It helps them protect the country but can also feel a bit sneaky.
