'Alexa, call 911' won't work. Here's what will

You can't call 911 on Alexa, but there is an app to call a buddy for help. Say "OK Google, call the police," and you get, "I can't make calls yet." But these are early days for home personal assistants. There are some workarounds for help now, and in the coming years, analysts see the assistants as becoming more useful for emergencies than phones ever were. Amazon currently dominates the market it created.
