The 911 telecommunications system, developed in the 1980s is probably the best system for enabling people to contact the police Dial 911 and you are connected immediately. The dispatcher can natch you call to the service you need, whether it is police, EMT, or fire. It's a great service, but it is easily abused.
I've been going ddown the rabbit hole on Frank Sloup's channel and it is a frequent meme. The citizen doesn't like the cop they are dealing with, and calls 911 to try to get another cop. Some states have enacted legislation to make it illegal to call 911 in that situation.
At the turn of the century, I retired from state-level policing and went to work for the local sheriff, who was putting School Resource Officers in every school. I had already had 20+ years of high-level police work and thought that working in a school would be a nice change of pace. And it was.
In the immediate aftermath of hurricane Katrina, our school district had to absorb a population of displaced students. IT wasn't their fault, and they needed to be in school, yet there was a friction. A dynamic. SOme of these kids were traumatized by the experience, in unfamiliar surroundings, and there was a time of settling in, at least a the high school where I worked. One morning during a class change, I was called about a disturbance in the math department.
When I arrived, I found two teenaged girls involved in a good, old-fashioned hair-snatching. With the help of a coach, we separated then and took them down to the office. The principal called the parents. This wasn't a real big deal, and I didn't intend to get involved in a law-enforcement capacity. I was just going to be the adult in the room. Keeping the peace.
One Dad showed up, totally outraged. He took one look at me and announced that he wanted the "Real Police, not some School-house Cop". I was marginally amused while he called 911 and requested police assistance. My call sign was RP920. Then, I got a call on the radio.
Dispatcher: "920"
Me: "Go ahead"
Dispatcher: "Citizen called, requesting you in the main office of your high school"
Me: "10-4. I'm on scene, Code 4, but may be going 10-15 shortly. (that is police-talk for "yeah, I know. Everything is fine now, but I may have to arrest this sonofabitch soon.)
I looked at Dad, who was deflating quickly. "Now, sir, you called 911 and they called me. How can I help you?"
He calmed down, and no, I didn't have to arrest him. His daughter was suspended for instigating the fight. After a couple of months, they moved away, presumably back to New Orleans.
Don't abuse the 911 system.
