Rural areas are far from not having crime, it is just much of it ends up not getting reported because by time the cops come, it is over, the people at fault are gone, and the cops got nothing to do other than harass the non-criminal people that are dumb enough to still be around. Rural police are 90% a money-making racket and the people know it. Threatening to call the police on someone in a rural area is considered a worse threat by most than directly threatening someone with a beating or deadly weapons.
If your tractor gets stolen, the only reason to call the police is for insurance purposes. Otherwise the only way you are likely to ever see that tractor again is to ask around and look for it yourself. Plus you gotta be pretty dumb to steal a farmer's tractor. Not only is it noisy as fuck, extremely obvious, and will take forever to actually get anywhere, but the person stealing it is at the mercy of the farmer that has all the time in the world to come out and either force you out by gunpoint or blast you from a half mile away.
