Maybe AI image recognition is good enough by then to actually determine if it is from a human or some other animal, so that you know beforehand that your paperwork will not be in vain at least. I don't expect that there will be much of a police investigation, the age should be rather obvious in most cases. On the other hand I've heard that there are states where the police get less than half a year of training, so maybe there will be one. But still, think of the potential scientific value :)
