Last week, when Trump federalized Washington, DC's police force and deployed the National Guard to occupy its streets, one of his main orders was to "end vagrancy" by destroying homeless encampments and arresting and forcibly relocating the people taking shelter there. But according to an investigation published on Wednesday by Hanna Homestead of the National Priorities Project, in collaboration with The Intercept, deploying the National Guard and "getting rid of the slums" is costing far more than it would cost to simply provide housing to every homeless person in the city.
