They're pissed off at their phone, and reaching for the biggest stick they can find -- not to fix the problem, but to punish whoever caused it. Likely, they wouldn't even punish the right person, it would just be a scapegoat sacrificed to appease their wrath.
Your comment is right on the nose when it comes to thinking rationally, and not emotionally.
A smart phone is not like the flight computers on a 747. If you want guaranteed 911 access with the threat of criminal prosecution if it fails, I'll happily design you a device. It will cost $50k, and will have a monthly service fee of $1000 per user. It won't have any other features besides 911. But it will work!
People just don't know what they're demanding.
