A question has come up as the result of some recent events that are too low profile to be major news. A film location crew, exploring out in the desert, came upon this abandoned house. The house had a cistern, and in the cistern was a badly burned human body. So badly burned that somehow when a family said "that could be our missing family member" the coroner said "why, yes, it seems that it is" even though it wasn't. The body remains unidentified pending a DNA test, but it clearly isn't the missing person it was thought to be, since another city in the region informed the distraught family that it clearly wasn't their person since he had recently been in their custody on a vagrancy charge. Now the family, who has been on a serious emotional roller coaster is again searching for their missing family member, who may or may not even know that he has been reported as dead and then miraculously reported to not be dead. It is true that if the family were to be well informed, reasonably skilled, and willing to make the effort, it is possible to scan booking reports from all the various counties and cities for a lost person, and those booking reports might even be updated fast enough in many cases to know the person has been picked up on some petty charge like vagrancy before they are cast back out. You'd have to be lucky and on the ball, but maybe. Anyway, this is the question... If a person obviously of no means is picked up for vagrancy or some other "get the homeless off my lawn and keep them for a few hours" type charge, should law enforcement be expected to make an effort to contact their people whether the person being charged wants them to or not? It isn't technically any kind of legal "invasion of privacy," since as noted the booking record is available on-line anyway. It's just a question of going out of the way to call attention to a piece of already public information.
