You listed so many different types of missing people, how is it that you could possibly believe that someone could create an effective one size fits all process. When foul play is suspected would require different approach than if no foul play, a mentally ill person would need more urgency than an able mind and body person. Plus this guy, I believe I read it is not entirely out of character for him to not be in contact with his family for long periods of time. Again, I hope he is found safe, but there is no reason insinuate wrong doing by the police based on race.
