As for someone just dragging my truck out of the driveway with a hook, not much I could do. But if I saw it happening, my .357 will make short work of the engine block, which is what it was developed for. Maybe some tires, too.
No need to cap a perp, they're recorded by my camera setup...
unless they are wearing masks.
Maybe keep my pickaxe (or my 5 foot long prybar as a javelin) by the front yard and punch through the grill into the radiator.
Of course, they're going to show up at oh-dark-hundred, when everyone is asleep, including this old man.
