As you say, it's pretty evident from watching the television program—which I didn't see, by the way—and listening to these gentlemen here today that there can be benefits from the knowledge that already exists about the positive aspects of a relationship between animals and humans, particularly in the case of PTSD-type symptoms.
Why wouldn't you provide that assistance to people when the benefits are obvious, even if it may take a long time and a lot of money to scientifically prove those benefits? Meanwhile people are hurting.
