"justice" 1870's-1930's

The late Paddy Tucker independently stated that he believed Willoberta Jack to have been poisoned. As he explained, from the 1870's-1930's no Aboriginal or person of Aboriginal descent could expect to escape if he or she killed a white person, even though the killing might be in self defence. There were always some white people who would ensure that the Aboriginal person was killed in the name of "justice" and "keeping the niggers in line".

Background information: Willoberta killed Harry Henty in the late 1920s after Henty attempted to shoot Willoberta because Willoberta refused to allow Henty to rape his underage daughter. Willoberta went into hiding for years and when he emerged was found not guilty by reason of self defence. But later on a fella by the name of Jimmy Donu gave Willoberta a bag of flour in which poison was chucked in before the flour was put in.
