Yes, they did.
The Home Office actually spent two years and £3 million. They did the same type of protocols, and they are now collecting the field data as well. When they went out to the initial use in 2003, I believe it was, they only limited it to five agencies. It was very controlled, and I believe it was over 18 months where they were very controlled in the use.
In France, where this unit is used by the police in the gendarmerie, they did do human testing prior to allowing the law enforcement...following the protocols that had actually been done in both Canada and the United Kingdom. There is a lot of sharing of knowledge among the countries and institutes of justice between Europe and North America, and in Australia the Alfred hospital had done the same type of research. So it's not just research that's been done in the U.S.; there has been human research done outside the U.S. as well.
