For the most part, police officers have no underlying legal duty to save your life. There are a couple exceptions, but dirtbags fleeing into a marsh/pond is certainly not one of them.
Also, since we don’t have all the facts, it might be possible other officers not in view of a dash cam attempted the rescue.
