Certainly at times TR's admonition to "Speak softly, but carry a big stick" is attractive, as is gunboat diplomacy. Sadly in the scenario you posit, an American shot on US soil by "diplomatic" personnel, our laws might not have any clout. There have been many incidents of those with diplomatic immunity involved in hideous auto accidents and we couldn't prosecute. I don't know whether any deaths were involved.
