My brother has actually urged a home defense plan, for reasons not relevant to a public discussion, with multiple concealed but quickly accesible instruments of force allowing a graduated response. He also advised it is easier to put down a shotgun or use its weight as an improvised weapon than to get it if the initial evaluation of need was incorrect. Something to be said about the deterrent effect of a shotgun being pumped being one of the few things for which we can thank Hollywood.
