I hate to sound like a doubt-er, but I think I'd have to see his DD214 to believe he is ex-service, much less viet vet. The reason I say it is because of his expression when being questioned by the reporter, and I would think most would answer something like " yea, Army, '66-67", or some such. I've seen too many street people making false claims.
But, either way, it was nice to see a percieved victim getting the upper hand.
