The fact that they are vets is important. That fact would get me to help out providing shelter for the guy, or buying him a tent so he can live in the woods. (As opposed to your average loser bumb, who I really have no sympathy for). This guy is mentally ill because when asked to go to war for our nation, he went. I have respect for him, and would be willing to help him. However there have to be limits. Im my opinion, staking out a public memorial as your own turf, and having a vicsious dog to protect it is beyone these limits. Yes he is a veteran. Well, what about the grandson of a vet who wants to see the memorial, should he have to put up with a vicious dog? What about an old man on a cane, who was a WW1 vet. Should he be allowed to vist the memorial without fear of being attacked by a dog?
