You watched an attack, that started outside of Hooters, by multiple youth against one or two adults, that sought refuge inside Hooters. Outside, was the place, where an armed citizen under attack by multiple people (whether youth or adult) would have been justified as stand your ground or self-protection from threat. In that situation, I would shoot my attackers, as at 68, I no longer have the strength, speed and endurance to successfully compete, and withstand such an assault, regardless of the age of the attackers, and would do it without shame or hesitation, as it is possible, that to hesitate is to die. Failing to do so, due to the age of the attackers would be a foolish act of self-shame. The age of innocence is gone. Youth are lethally dangerous, these days, something we see in the news every day. Better to face the papers and a jury of 12, than be carried by 6.
