Two German shepherds and a local dog. Three guns. A large assortments of blades, taser, CCTV.
If somebody got close enough and was not armed with a gun would I use what I have learned in Budo? Of course. But it is 2016. Here and now they will even use crystal meth to hype themselves up before an assault.
Do we feel threatened? Not in the least. Just precautionary measures.
