The family of Oscar Pistorius,the double-amputee Olympian charged with murdering his girlfriend,is feuding publicly over whether guns are a necessary protection against crime in South Africa. British newspapers quoted Pistorius father,Henke Pistorius,as saying the family owns handguns for self-defence and suggesting that South Africas government shares blame for white crime levels. In a statement Tuesday quoting the runners uncle,Arnold Pistorius,the family subsequently distanced itself from the fathers comments.
