That's how it sounds, especially when she said, "You know how these families get." And the news report says she wanted to wait for someone else.
But, if she was afraid, she shouldn't have been an EMT.
This does make me wonder now... Where I live, I've called 911 twice for a medical emergencies. Both times, the police arrived first before the paramedics. That seems to be the policy. Now I'm wondering if it's policy for the protection of the EMTs. What would happen if the police car didn't arrive first?
