Again, for us, the veterans we are aware of are self-identified. We don't even know if they're truly veterans or if it's mental illness that's coming into play and they're assuming that identity for whatever reason.
In general, my experience with the homeless, from working in operations, is that these people are a vulnerable sector of the population, and there are predators out there who prey upon them. For the ones I have met who have, in their past life, been of some stature of strength and ability, there is shame associated to that, to how somehow they've let themselves get to this point where now they are the person who's being beaten upon, the one getting taken advantage of or extorted or whatever. The victimization, whether it's reported to us or not, does contribute to a sense of self-degradation. It lessens their self-worth.
