I think the key one is the obligation of another state to provide support to the country's nationals in difficulty in that country. The most serious part of all of this, of course, is the people who are arrested and in jail, and some sort of a judicial process is under way for them. It is in that area where I think there is the biggest need for change.
Right now one of the few elements in the Vienna convention that I think is good is limited. The person detained has to be told by the arresting state that they can contact their consular authorities, but too much flexibility is left to the arresting state as to whether or not, in effect, a Canadian who is arrested—even in Texas or Arizona, for that matter—is informed of his or her right. Back a few years ago, we went to the Supreme Court of the United States with an amicus brief because a Canadian was executed in Texas, and that Canadian was not advised of the fact that he could contact the Canadian authorities.
It's in that area that I see most of the changes that I think would be important to most Canadians.
