I understand. It makes me uncomfortable because some jurisdictions, some countries, I would suggest--based on some readings I've done--use psychological profiling as opposed to racial profiling. I would find that extremely disturbing and I think most Canadians would.
You're suggesting that someone who's paid, as Mr. McGuinty put it, in the neighbourhood of $12 an hour is able to do some serious psychological profiling on behaviours or otherwise, which the RCMP, for instance, are trained on for six months. I would find it extremely unlikely that you would find the quality of people necessary to do that after the training, with a 15% turnover.
Again, those are only my comments.
