The onus is on the woman to articulate her need to defend herself, in this instance by using threat of deadly force. Without knowing the facts of the case and only what is described above, she could very likely face civil and/or criminal charges, especially in the 9th circuit.

"Offensive" is highly subjective and for the most part not a standard used by the courts. "Reasonable" is a standard defined by the courts.
