I watched the video front to back, and the mother participated, no doubt not wanting to displease her husband by being less-than supportive. I have spanked my children, but by the time they are teenagers, especially girls, spanking is a non-starter. I can’t remember spanking a child older than four or five, and never for something trivial like being on a computer after hours. The judge crossed the line, and if he could appraise his daughter’s video-capture as a disinterested third party I’m sure he would be impressed.
He definitely went way overboard for sure, but this wasn’t about ‘being on a computer after hours’.
From what’s on the video, she was repeatedly installing a file sharing application and downloading pirated content. She had obviously been told to stop previously and didn’t.
She blithely told her mother “well, I’m sorry, but it’s easier than paying” while her father was going to get the belt.
