amber alerts on cox TV

Why are my shows interrupted by this alert 4 times last night, it over rode my ability to shut off the cable box and about blew out my hearing aids with the sound level broadcasted with the alert. i have has cable with COX for almost 20 years and this has never happened before, it is also not a requirement of the government, as suggested by one of the moderators, it is an option, the only thing mandatory is a presidential notice.

i highly doubt that any such alert will find anyone in my living room and i don't expect that i will run out of the house at 9:30 PM to look around the area.  

i would like to Opt-Out of any amber alerts, and if i cannot, i may have to consider other options to your service
