The kid was thrown off like a 20 ft balcony he most likely would have lived but been seriously injured. Not dead.
I do not want to extend the argument, but a.) That makes little difference b.) The dummy was tumbling through the air when it hit the ground. Depending on the angle he hit the ground at he could have been anything from severely injured to killed. That is a very large and morbid range of injuries and none of the outcomes are pleasant. and c.) You are not an doctor. I do not trust that you are adequately informed on the survival rate for toddlers falling from twenty feet.
