I'm not sure what incident you're referring to. e.g. See https://www.youtube.com/watch?v=-r2oaQWmqkk https://www.youtube.com/watch?v=-r2oaQWmqkk, there's no swooping, and no indication that the ship was "on maneuvers." Navy ships and aircraft can't help being near commercial aircraft much of the time, and vice versa, since flight paths crisscross the whole world. But whether they "deserve to be shot down" or not (a highly questionable moral position I think), it would be pragmatically unwise to do so. You will either create a domestic political crisis that will shake up the whole military, or an international incident, depending on the carrier.
