The only priority of law enforcement - its mandate even - is to locate and prosecute those who have broken the law. They may empathize with victims and victims' families, and even go out of their way to be sensitive to their situation, but their technical procedures and protocols don't take those things into account. Sure, one of their goals overlaps with the family's goal of finding their loved one, but not for the same reasons.
How many times have we seen a family trying desperately to obtain information about their missing loved one from law enforcement only to be rebuffed, and in some cases, ignored altogether?
We should not ascribe altruistic, compassionate intentions/priorities to a government body that is, by design and by mandate, supposed to operate independently of those things.
