c. The discharge of a firearm, other than a firearm loaded with less lethal munitions and discharged by a peace officer, corrections officer, or corrections official in the line of duty, in the direction of some person with the knowledge of the person’s presence there, even though no intent to inflict serious physical injury can be shown.

d. The discharge of a firearm, other than a firearm loaded with less lethal munitions and discharged by a peace officer, corrections officer, or corrections official in the line of duty, at a vehicle in which a person is known to be.
