Pity Ms. Porter's letters no longer will be posted: they're an excellent example of naive/ misplaced caring. It is obvious to all but the most non-observant that there isn't one homeless group: there are several (or more). The most clear: older unhealthy looking guys w/clearly visible drinking/drug problems; women or women w/children who (mostly) are victims of domestic abuse or desertion; young people who are apparently hale-and-healthy but voluntarily have adopted the "traveler" lifestyle often w/musical accompaniment and dogs; very strong-looking men in their 20s-early-40s that walk around w/huge backpacks; obvious criminal types that hang around the travelers in the downtown ground-zero bum area.
I haven't read any mail directed against any of these groups except when they have grown to become a threat and a menace to ordinary citizens who merely wish to enjoy their downtown w/out feeling endangered. Murder, assault, and aggressive behaviors must be tolerable in Porter's world.
