Looks like Mrs. Hopkinson doesn’t know she can stop keeping an eye on her shop.
As always, can’t say if it’s real or not. I do find it interesting, however, that they couldn’t find a better way to get the proof than to film the screen that shows the footage. Could be because they aren’t tech-savvy investigators, just regular people who caught something and didn’t know how else to get it across. Or, they are extremely tech-savvy, CGI or photoshopped the whole thing and wanted to downplay their expertise. You be the judge.
