Disabling alerts is the second thing I do to a new handset (after rooting) - including Presidential alerts. The Amber alerts I got were often hundreds of miles away. But even if they were closer - say only 25 mi away, I'm still not going to be any help. Weather alerts weren't much better. Having my device sound the klaxons over Red Flag warnings conditioned me to ignore all alerts.
