that she genuinely thought she had been sexually assaulted and that needs to be investigated
Did she really think that, though? I wish we knew if she was serious or not.
If she didn't think that, then calling the police would be out of malice to "get this kid and his mom." It would also mean that she knew it was the kid's backpack that touched her butt. On her call to the police, she tells them there are surveillance cameras and that they need to check them. If she knew it was the backpack and knew about the cameras, then she would be setting herself up.
It is possible she did it out of malice. When the police check the surveillance cameras and find out it was his backpack, she could easily say she thought it was his hand, still. It is also possible she was just trying to instigate something. But I have no idea if she actually believed it or not. It seems weird for her to really think that was what was going on... But, IDK...
Right, but what would the point be to call the cops if she knew there was nothing to "get" them with? ---
