I don't do much diagramming anymore. Is that why I fail to see any ambiguity here? It seems plain to me that the subject shot at an object who had done A and B. It also seems, as someone else has noted, that it would take very convoluted thinking to read it in any other way.

I read a headline at Crime Library's Daily Crime News within the last wek or so "Boyfriend fingers prostitute". Now that's ambiguous. Or is it ambidextrous?
