You could argue that it is poorly made but perhaps the model was trained in a rush because it was a cheap, knock-off produced en-masse for school-scale.
Even if its well-made; imagine you're some 1 in a 1,000,000 non-typical. Who is the school going to believe, some irksome child or the system that works perfectly fine for 99.99% of other students? "Obviously" in such a case, the child is lying and just needs to learn to pay attention.
