Video proof to the importance of the 2nd amendment and the right to protect yourself with a firearm

As you can see in the video below, a group of 12 men approach the school in the bed of a pick up truck. As the female students start to flea, an administrator armed with a handgun emerges from the building sending all 12 assailants fleeing in various directions.
None of the students were hurt in the attack but three of the attackers ended up in local hospitals.  Authorities were able to arrest the attackers who needed emergency care.
