They do not have the right to roam when our tax dollars are going to free housing, phones and healthcare while actual citizens of America struggle to survive. Also, have you seen any of the news reports regarding all the violent crime many have committed? I'm not saying all of the illegals are criminals people, but many are and we have no way of knowing which are and aren't without an actual immigration system in place. So "Humans have the right to roam". I don't think so. We need a wall.
