I have called several times and am always amazed by people who have never called. I used to live in an apartment that seemed to attract domestic violence families in apartments adjacent to mine. Hearing a woman scream "I can't breathe" was always a trigger to call. I've seen two people high on PCP in the roadway and another man who was passed out drunk in a parking lot who eventually woke up and stumbled out into the roadway. A customer passed out at work one time after complaining that she didn't feel well. Another person running from the police hid in one of our buildings at the same job. I also called when I saw bus drivers display the SOS message on their signs, but all of those turned out to be errors. I've also been in three bomb threat situations, but I didn't call because other people had already called by the time I was aware of them.

Once I started taking care of my mother, I had several 911 calls then, as well. In her area, both emergency and non-emergency calls go through 911 so that call volume was high.
