Two US lawmakers have introduced legislation that would help expand the AMBER Alert system to all territories, which include American Samoa, Guam, the Northern Marianas Islands, Puerto Rico and the US Virgin Islands. Established nationally in 2003, the system sends alerts over TV, radio, digital billboards and cellphones and has helped find more than 900 missing children across the US. "AMBER Alerts have helped save hundreds of children. There's no good reason for US territories to be excluded from this system," said Senator Brian Schatz (D-HI), who introduced the bill along with Senator Lisa Murkowski (R-AK). "With this bill, we can help children and their families quickly end the nightmare that is child abduction."
