At least in France there is a history of hatred and ego between the Police Nationale and the Gendarmerie. Since they do the same work, do not share and duplicate the efforts it wild make sense to just merge them. But that would require some people to let go kingdoms. Having worked extensively with both, the way they are organized today is a pity.
