Oscar Pistorius should have taken the court into his confidence by testifying at his bail hearing, prosecutor Gerrie Nel said as the athlete's bail application continued at the Pretoria Magistrate's Court on Friday.

"He has the right," said Nel.

Pistorius could have given his version of the shooting of his girlfriend Reeva Steenkamp, not just by an affidavit, and been tested on his version of events, said Nel.

Nel said Pistorius did not appreciate the seriousness of the crime.

"I have not seen anywhere in his affidavit where he says 'I caused a death'," he said.

Pistorius has denied deliberately shooting Steenkamp on 14 February and has said he thought there was a burglar when he fired shots at a toilet door, killing her.

He never said he "at least" caused Steenkamp's death unlawfully, said Nel.

Pistorius has been charged with murder, which he denies.

Nel said that not volunteering to surrender his passport to show he was not a flight risk showed "it was business as usual" for Pistorius.

Nel has questioned the details of Pistorius's version of the moments before he shot Steenkamp.

"For a woman who went to the bathroom at 3am, and someone who shouts 'there is an intruder', the woman would have said 'Oscar where are you?'," said Nel.

On Pistorius' version, Steenkamp must have pulled up her shorts when she heard him screaming and locked the door, said Nel.

The court has heard in initial evidence that Steenkamp's bladder was empty and Steenkamp was wearing shorts when Pistorius carried her downstairs before she died.

"To find this version probable, one must stretch," said Nel.

Pistorius looked down as Nel continued his argument opposing the granting of bail.

Nel wanted to know why the two did not bump into each other with him fetching a fan on the balcony as his affidavit said, and her going to the toilet.

"It's always very easy to give a version, especially where there is one person to give a version."
