They do have a booklet. They do have information available online about your rights when detained abroad, and they do caution that conditions are not the same as they are in Canada. Global Affairs' approach to this is to inform the travellers.
Our issue was that they had not examined the best way to reach the vulnerable travellers, nor had they examined their outreach to people who might be travelling to dangerous locations or to the Caribbean during holiday or hurricane season. They need to know how to best reach them and how to best put that information online. The fact that it's online and there's a booklet available to you after 15 clicks may not be the most effective way.
