Defined agree that this was a heinous act. But it seems this person or group of people took multiple measures (Christmas morning, gun shot sounds, verbal notice of intention) to make sure civilians had notice and time to get to a safe distance. Just seems a bit odd and unprecedented that an act like this was carried out with explicit intent to minimize civilian harm and casualties. Will be interesting to hear more about what actually happened, by whom, and their motives, if any of this ever becomes known.
