What was made effective by an Executive Order signed by Charlie Crist on October 8, 2008?

The correct answer is the Silver Alert, which was established to aid in locating missing vulnerable adults, particularly those with cognitive impairments such as Alzheimer's disease. Executive Order 08-145, signed by then-Governor Charlie Crist on October 8, 2008, specifically authorized the Silver Alert program in Florida. This initiative was designed to create a rapid information dissemination system that helps local law enforcement agencies to locate and rescue those who may be lost and incapable of looking after themselves.

The Silver Alert is similar in concept to the AMBER Alert, which focuses on missing children, but it targets a different demographic. By implementing the Silver Alert through executive order, the state recognized the critical need for immediate action in cases involving vulnerable adults, thereby fostering a swift response that can potentially save lives.
