Another friend told how Pistorius asked someone else to take the blame when a gun he was handling fired under a table in a busy restaurant.
At the start of the trial, the defense objected to what they call inadmissible evidence that amounts to character "assassination."
While the first five days of proceedings were dominated by doubts over Pistorius' character and some of his actions on the night of Steenkamp's death, the defense has sought to poke holes in the prosecution's case about the sequence of events: It says it can prove that Steenkamp did not scream before the shots and could not have screamed during them, as witnesses have said.
