If she dumps the clip most likely a jury will consider that excessive force. Whether or not she hits anything or nothing. In NC the law reads " use of deadly force can be used when threatened with death, serious bodily harm, to stop forcible entry,or sexualy assault to a person with normal fortitude" or to some extent thereof. Whos to say whats normal. What my not bother me could scare the crap outa someone else and vice versa... My CC instructor taught us double tap center mass if you miss and perp is still advancing repeat until he's down or runs away. NEVER JUST SHOOT TILL YOUR EMPTY!!! then it becomes excessive force. Don't tell the police you were trying to kill the perp or that you were aiming at his head/heart. A DA and jury will take that and charge you with murder or manslaughter.(excessive force again). When questoined simply say you were aiming center mass and was just trying to stop the threat. I mean the guy that broke in your house at 3 in the morning with knife/gun might just want to show you his new toy (yea right).
