I'd talk to the neighbors emphasizing the danger to local pets as well as them deciding humans=food supply. You might find that you suddenly have several willing lookouts.
No bull, I was in an area similar to that(suburban next to rural) and had the coyotes starting to follow my kids if they were in a certain area at dusk. This situation has all sorts of nasty possibilties in terms of danger. It's late for them to be raising pups but be aware that it is remotely possible. Where I grew up 'yotes were hunted quite often from a considerable distance with any centerfire varmint round. Sounds to me like a perfectly logical reason to buy and scope such a rig, after all it's for the greater good
