If it had the ability to override silent mode or do-not-disturb, I'd hope they use their discretion depending on the type of alert.

@TurdFerguson a little, yeah. I'm okay with it, assuming I'm understanding how it works correctly. It's just a bulk push notification to all devices that are connected to the cell network (and customized based on where, physically, they are connected), so it's no more big brother than everything they can already do if you're on the network.
