Gun quiz read at Oscar Pistorius murder trial

The Oscar Pistorius trial has heard from a firearm specialist who testified the athlete had good knowledge of the rules on gun use and dealing with intruders.

Sean Patrick Rens is involved in firearms assessment for licences and met Mr Pistorius in 2012 through a mutual friend.

In court Mr Rens read out a competency questionnaire and examination that Mr Pistorius, a South African athlete, had completed before he could be issued with a firearm.

Mr Pistorius denies murdering his girlfriend Reeva Steenkamp last year, saying he mistook her for an intruder.

The prosecution says he intentionally shot Ms Steenkamp after an argument at his house on Valentine's Day 2013.
