In the video you see the officers running to action to save a 26-year-old driver, where those flames are burning. You see a guy kind of milling around, unsure of what to do, but police didn't hesitate, they spring out of their vehicles and run to help save that person, then hear as one of the officers calls out for more help and more extinguishers.
They were able to get that victim out and knocked the fire out a few moments later.
