  You're right, my explanation was technically inaccurate. However, the terminal velocity of a bullet due to gravity is still easily enough to kill someone (and does kill every year from people "celebrating" this way), so my point still stands.

  When rifled bullets are fired in parabolic trajectories into the sky, they retain enough horizontal velocity to easily kill. There are numerous examples of people being struck and killed by bullets that were fired into the air (typically in celebration of something inane). Lightweight rounds, such as birdshot, are safe when fired into the sky. That is the exception.
