I still don't know, but if the government is protecting us from weapons mongers, it would be nice to know the size of a single "mong". A recent official training memo for one DHS fusion region identified a total of seven weapons as a "cache", so we're starting to make some progress in decoding federal terminology. I still don't know if quantities involving cache, hoard, stockpile, arsenal, etc have any overlap, or if some weapons count as more or less than one in determining the count. But we now know that in at least one DHS security region, you can be arrested for having a "weapons cache" that totals seven firearms.
The media throws these terms around very sloppily, but in this instance, even though there was no prosecution, an authorized DHS contractor sent out an official training memo to the whole region, confirming that seven weapons are officially considered a "cache".
As far "home defense" goes, I have some form of blunt instrument within reach at each door, hidden in the folds of a drape. If that fails to curb their enthusiasm, I can produce a high-speed crowd pleaser in less than thirty seconds. :)
The thing I especially liked about the hanging basket was that the rim was a nice six foot above the floor. A small child couldn’t reach it and an adult would never put their hands into it unless they knew what was to be found there. To all outside appearances it appeared to be simply a flower basket.
