My nice neighbor lets a fellow live in his van in the back driveway, where he meets his friends and putters around. The fellow and his buddies are sketchy — as far as I can tell they drive around finding things to sell.

If I complain to my neighbor, the fellow or his buddies might retaliate. It would be easy. If I call the cops or landlord, my neighbor might get evicted, and I don't want this.

I feel pretty stuck. I want my backyard privacy back. What would you do?
