Okay kiddo, have you ever seen a police officer's uniform? They usually have a patch or badge on their shirt that says "Police" or has a design with the name of their department.
Some people really like to collect these patches like they're stickers in a scrapbook. They might collect patches from different departments or even different countries.
Collecting police patches can be a special hobby because it's a way for people to show respect for law enforcement officers who work hard to keep us safe. It can also be a way to learn about different types of police departments and the different jobs officers do.
Just like with any collection, people can trade and buy patches to fill out their collections. Some collectors might even display their patches in a special frame or album, like a picture book.
It's important to remember that while collecting patches can be fun, it's also important to respect the work of police officers and the badges they wear. It's not okay to try to impersonate an officer by wearing a patch or badge that doesn't belong to you.
