Hidden Camera S

When I do Hidden Camera pranks in stores or wherever, do I need the people’s in the video permission?

Do I need people that I prank’s permission to use them in my video even though I am not putting it online like on youtube. If I am putting it online do I need their permission and do I need the store’s permission, too?

It depends on what kind of prank
