I have known of two such attacks where people I know were involved.
In both instances, the victim pulled his gun on the attackers and frightened no one. Attackers in groups are usually trying to prove themselves to one another, and if they feel fear they are many times unlikely to show it.
In the one instance, the victim shot one of his attackers and the attacker still persisted.
In the second instance, the victim was met with yells from the attackers to "Pull that s---!"
Luckily, in both cases, the victims got away, barely.
I urge you all to research the case of Gerald Ung, who, while wolf-packed by several bullies, showed his gun, and was forced to unload into one of the assailant's torso.
Had it not been for a security camera that captured the events leading up to the shooting, he would be in jail to this day, because it was the attackers' word against his.
I know... you'd rather be tried by a jury of 12 instead of carried by six, but what way is it to live 20 years in jail for defending yourself?
Just be careful and use good judgement.
