Assault or not assault

[jungleoutlaw]

I am requesting opinions on four scenarios, one of which is true.

1. A group of high school boys attending an after school activity, bring an airsoft pistol into the school with them. They corner an unsuspecting fellow male student and proceed to shoot him, with the airsoft pellets, in the back, butt, chest and genital area. Then the pistol is pointed directly at his eye and threatened to have his eye shot out.
2. A group of high school girls attending an after school activity, bring an airsoft pistol into the school with them. They corner an unsuspecting fellow female student and proceed to shoot her, with the airsoft pellets, in the back, butt, breasts and genital area. Then the pistol is pointed directly at his eye and threatened to have her eye shot out.

   Is there any perceived difference in the scenarios due to sex of the perpetrators and the victims?
   Is it bullying, assault, sexual assault, criminal or just a prank gone to far in each of the cases?
