South African 'Bull Dog' prosecutor made famous by Pistorius trial resigns

South African prosecutor Gerrie Nel, who oversaw the conviction of Paralympian Oscar Pistorius, has resigned from the National Prosecuting Authority (NPA), its spokesman said on Tuesday. During the Pistorius trial, Nel painstakingly crafted a picture of Pistorius as a cold-blooded killer who fired through a door at his cowering girlfriend. For his no-nonsense attitude, Nel earned the nickname 'The Bull Dog' as a prosecutor.
