How federal involvement will help? Article doesn't detail what powers exactly federal govt possesses that would help, aside from moving spending from local to fed level. I'd also argue, that having feds in this business would even worsen the situation: now locals could be taken completely out of the loop for decisions like where to place shelters. Like, "oh you don't like shelter in this neighborhood? take a walk - it's a federal decision, live with it."
