I am not advocating for large scale facial recognition, but your argument holds true for basically any measure law enforcement has to apply to locate missing people.

How big is the false positive rate with tips received by phone? Law enforcement probably has to deal with much more wrong clues on a daily basis than to double check an image that was flagged by an automated system. And if even a human inspection can't tell the difference between the missing person and an image of the missing person then it's definitely worth checking out.
