Milwaukee - a young mother with two young children in the car loses control of her vehicle and hits a tree. The car ends up on its side and bursts into flames.
The mother and one child make it out fairly quickly, but one child remains inside, strapped in by his seat belt, burning alive.
In this video you can hear the brave men, off-duty fire fighters, who rescued this young child calling desperately for a knife to cut the seatbelt. If you don't carry a knife, or a rescue tool (much less an emergency kit, c'mon people!), in your car please consider doing so. Here are a few examples:

All passengers made it out alive, and the boy, although he suffered severe burns, is expected to make a full recovery. The rescuers did sustain burns in freeing the boy from the car.
Finally, note that the cops don't arrive until the end of the video -- long after the boy, and possibly the mother and other child, would have died.
