a few months ago someone accidentally posted an amber alert to the presidential alert channel here in my province and that was the first time I had ever heard of something like that. So I researched it

>Such a presidential alert has never been sent, but since 2006, theyโve been unblockable by law. Thatโs when President George W. Bush signed into law the Warning, Alert, Response and Network Act, which provided for the Wireless Emergency Alertโs creation. The law made it mandatory for wireless companies participating in the system (nearly every major wireless company has voluntarily opted in) to make presidential alerts unblockable on cell phones and other devices that use cell data, like iPads.
