Try to imagine what it may feel like to be inside the helmet of a Kenyan police officer walking the streets in Haiti's capital.

You don't speak French or their patois version, weapons are everywhere, ordinary citizens are frightened and angry, those with weapons are inclined to shoot first, think later, you are unsure of your own country's plan for how to clean up the mess, your fellow officers who are, like you, trying to do the right thing, whatever it might be.

To make it more interesting, the armed gangs and their bosses know that foreign police officers are going to try to make them lose their power.
