Despite any claim they make, police and EMS are second responders. You are your own first responder.
Keep weapons around. They don’t have to be guns they can be hammers, other tools etc... but it’s good to keep stuff around the house so you know where it’s at if you’re scrambling inside your home while somebody’s trying to stick a knife in your guts. At least you got a little something for them if you’re not actively carrying inside your own home.
