A person commits an assault when, without justification, the person does any of the following:
(A) Any act which is intended to cause pain or injury to, or which is intended to result in physical contact which will be insulting or offensive to another, coupled with the apparent ability to execute the act;
(B) Any act which is intended to place another in fear of immediate physical contact which will be painful, injurious, insulting or offensive, coupled with the apparent ability to execute the act; and
(C) Intentionally points any firearm toward another, or displays in a threatening manner any dangerous weapon toward another. (A person who commits an assault, as defined in this section, with the intent to inflict serious injury upon another shall be guilty of an aggravated misdemeanor.) Provided that where the person doing any of the above enumerated acts, and such other person are voluntary participants in a sport, social or other activity, not in itself criminal, and such act is a reasonably foreseeable incident of such sport or activity, and does not create an unreasonable risk of serious injury or breach of the peace, the act shall not be an assault. (See Title B, Chapter 2, § 1.1 and Iowa Code § 708.1.)
