Because the term is from video games, meaning to lead an enemy around as if they were a kite that you are holding. Nobody is saying kites are older. And yes, you can say "let's go kiting" and mean playing with toy kites in a field, but that is not the definition of the word that is being discussed here. The guy kited the cop in the way that your marine would kite a zergling, not the way a kid would fly a kite at the park.
