Thank you for your question, Mr. Dubourg.
In my view, the first thing required is to stop supporting the current government, because it doesn't have the political will to solve the problems and that, precisely, is the heart of the matter. Unless the national police receives orders from the chief of the national police supreme council, the CSPN, it can't take any action.
The top priority is to get rid of this puppet government which was set up by foreign entities rather than by the Haitian people.
Then, I would reiterate that there are specialists in such areas in Haiti. The trouble is that they don't have the material and logistical resources. They need some mentoring in terms of training and practice. The national police needs to be structured in such a way that technical and tactical special units can be trained to respond quickly to circumstances.
Haitians should be dealing with the situation.
