I read this on Reddit:
Not a lawyer, but work for a law firm as an Investigator.
One of our clients stabbed an ex-lover multiple times over $100. Perp then ran out of the house all bloody. Neighbor and her teenage daughter see him covered in blood and rush inside to see if they can help while they call 9/11. Victim is still alive. On the 9/11 call the daughter made, you can hear the mom singing amazing grace while she tried to stop the bleeding. You can also hear the victim, with a stab wound in her neck, gurgling on blood while she tries to sing along.
The EMTs arrived in under 3 minutes, but it took the police 19 minutes from the call to show up to clear the scene for them. She lived for 17 minutes. I saw the photos of the scene with the body still in place. It looked like a scene straight from Dexter.
I find it shocking that EMTs would ever have to wait for police (except if they would be putting themselves in danger) before saving someone's life. Of course that someone writes about it on Reddit doesn't mean it actually happened, but is there any western / first world country where that is actually the law?
Edit: When reading through it again, it sounds like this happened in the United States. The currency in question is dollars, the story is written in perfect English, and an English song was reportedly sung. In which U.S. state could this have happened?
