Of course, those scenarios could happen to ANYONE who travels to a foreign country where they do not learn the language. Medical emergenices for those who have handicaps and cannot communicate are equally horrifying. If you are unconscious, the same issues.

I don't think anyone is arguing that people who live in a country would probably find life easier if they learn the "native" tongue, but I would draw the line at having my government enforce a rule to make it the law.
