Thank you, Chair, and thanks to both of you for coming.
I have a fair amount of experience with homelessness, as I practised emergency medicine in the inner city for a number of years. I know that in a lot of the homeless—not just vets, but the homeless in general—there's a very significant overlay of mental illness.
From what I've understood from some of the witnesses in other studies when they talk about homeless vets, many vets, due to mental illness or other issues, have more or less gone off the grid, in common parlance, and are very hard to find. Are there any statistics or is there any idea or estimate as to how many veterans might be unaccounted for and may be at risk? You might have a good idea that a person is out there and homeless, but do you have any idea of the numbers?
