Laager mentality

[Agnes]

The idea that since every man (and his gun) is needed for the common defense of the group, any [one mans] behavior, short of murder, must be tolerated, even including mild insanity and such serious crimes as rape. (From the Afrikaans voortrekker word laager - a circle of [wagons] forming a defensive [perimeter], as when the days journey was done and the group settled in for the night)
