Do you think homeschooling needs stricter oversight?

One of my co-workers is a bit off. She is always dressed sloppily, has a strange spacey look in her eyes, and is constantly talking about her 5 kids. Here is the scary part: she homeschools the children herself. I'm pretty sure this lady isn't quite all there. My family collected some of our unwanted items like clothes, old toys, etc., to take to my co-worker and her children. Tis' the season, right? When I arrived, I was faced with one of the most disturbing home scenes imaginable. Her children were out of control to say the least. As I walk through the door, I see 5 little heads pop out from various points, and then they start running around like crazed animals. They were screaming, pulling down curtains, and one of the boys was shooting a smaller boy with a pellet gun. Meanwhile, seated in the center of this chaos was my co-worker, with a giant grin on her face, "Hey! Don't mind the kids, they get excited when visitors come over." She grabbed one of them as he was running by, and the boy struggled like he was being abducted. Finally after he quit worming around, she told him to say hello to the guest. This is the part that breaks my heart, the little boy could only produce a "heh" type of noise. He had to have been around nine or so. How are we letting people get away with this horrendous abuse. I've seen success with homeschooling before, but this case certainly speaks volumes on just how much oversight needs to be present in the homeschooling system. In extreme cases it seems to be producing feral children!
