The same reasoning could be used to avoid interacting with everyone. It's not too hard to find stories of pizza delivery rapists. Always use caution, particularly with someone with typical markers for erratic behaviour, which homelessness in fairness counts as. Anecdotally, I've sat down and had conversations with innumerable people like that, and invited a few into my home. Few made me worried (other than for them). No one has ever attacked me. One young man tried to steal my wallet. Your mileage may of course vary.
