HyvaPaiva - I'm alarmed that you think that is the extent of the FCO's travel advice for Haiti. That is the headline summary.
Here's the more pertinent bit about safety and security (there are multiple sections of advice for each country), directly from the gov.uk site:
"Crime levels are high and the general security situation is unpredictable. You should seek advice from local contacts or established organisations and make arrangements for your security throughout your stay in Haiti. The presence of one or more travelling companions with reliable local knowledge can help deter any unwelcome attention and also provide support in an emergency. It is best to avoid travelling around Haiti alone.
Avoid displaying expensive items of jewellery or carrying large sums of money. Don’t leave property in vehicles and always travel with car doors locked and windows up. Park close to any venues you visit and where possible avoid leaving a venue alone. Avoid travelling at night. Extra care should be taken when visiting downtown Port au Prince."
And it goes on like that. Now, while it might not be Somalia, how is that not of concern for a traveler who is naive enough to think that they don't even need insurance??
I love travel, and I am generally in the 'life's too short' crew. But, there's taking calculated, informed risks, and then there's simply being completely unprepared. I would suggest, unfortunately, that she's the latter.
