Probably not good for her defense.
Just my opinion.
May have wanted to get a picture of the knife in case it disappeared.
The photo probably shows the knife in addition to the dead perp.
But the shot schmuck had to have been terminally stupid, to keep on harassing AFTER the victim digs out a firearm. He received the appropriate punishment for stupidity....removal from the gene pool.
She was probably recording the knife that was on the body or nearby, in case one of the guys friends removed it from the scene. Smart thinking....
pulled out her cell phone and recorded the body lying on the ground

Truly bizarre action. Was she planning to Tweet it to Geraldo?
Taking the picture for evidence?
When she says he had knife, she has the picture.
Nothing wrong with having a cool head.
