Lots of "us" have enough ammo and guns in our house to make the news. This really isn't a bad thing. Saying I have a brick of .22 bullets sounds reasonable, but when reported as "they found 500 rounds of shells in his house" some read it as an arsenal.
Bing, that's very true. My wife and I, along with my son and girlfriend, like to target shoot our pistols at the farm and that can easily burn up 300 rounds. We decided a long time ago that any family member that picked up a firearm would be completely comfortable and safe with that firearm. A 50 round box of 9mm in the closet won't accomplish that.
