Regrettably, Mrs. Marsden's comments are straight out of Hollywood, and buttressed by old and questionable data. Her reliance on what I presume is pepper spray (based on her description) is naive and optimistic. As a police officer over four decades, I've seen it fail. But then, if she's content with that, that's her choice. It doesn't mean it should be mine (it certainly won't), nor does it mean it should be yours. S.L.A. Marshal's study has been questioned with good reason ever sicne it's publication, and she would do better to read "On Killing" by Dave Grossman. She also conveniently chooses to ignore a wealth of documentation (even from government sources) that firearms are routinely and effectively used in self defense.
