I think there is an important educational aspect that can be accomplished, but not necessarily through the Criminal Code. It's much like someone who's going to be engaging in this type of behaviour probably isn't going to be deterred by this extra section. If I were a betting man, I would wager that someone who's going to engage in this type of behaviour isn't going to be even aware that this section exists. I think much the same can be said to the unwitting victims who aren't expecting and not seeking and not deserving of this treatment. I suspect that precisely what you call it...especially when you're not dealing with.... This is not a nuanced issue. If you're charged with torture, you have inflicted severe pain and suffering and damage on an individual, and I think it's more likely that an individual who is at the receiving end of that sort of treatment, whether it's called torture or not, is going to know that laws have been broken, that laws have been contravened, and the police should be alerted.
I would be skeptical about any increased reporting based on that.
