The Virginia State Police shall develop policies for the establishment of uniform standards for the creation of Amber Alert Programs throughout the Commonwealth. Amber Alert Programs may be local, regional, or statewide. They may include multiple localities or regions and may be expanded or compressed. The Virginia State Police may (i) inform local law-enforcement officials of the policies and procedures for the Amber Alert Programs set by the State Police; (ii) assist in determining the geographic scope of a particular Amber Alert; and (iii) establish procedures and standards by which a local law-enforcement agency may verify a child has been abducted and report such information to the Virginia State Police. The establishment of an Amber Alert Program by a locality and the media is voluntary and nothing in this chapter shall be construed to be a mandate that local officials or the media establish or participate in an Amber Alert Program. Existing Amber Agreements and Programs shall not be altered by the act of assembly creating this chapter.
