Okay kiddo, so copwatch is when people who are not police officers watch and record police officers doing their job. Like when you watch a police officer on patrol, or when they pull someone over, or when they are arresting someone.
The people who do copwatch want to make sure that the police are doing their job correctly and not hurting anyone or using too much force. They might also want to make sure that the police are not being unfair to certain people or treating them differently because of their skin color or where they come from.
So, the copwatchers use cameras or their phones to record what the police are doing. This way, if the police officer does something wrong, there is a video that can be used as proof.
Overall, copwatchers want the police to know that they are being watched, so they will be more careful and not hurt anyone. And they also want to make sure that everyone is treated fairly and equally by the police.
