seriously tho mike, why dont you knock on every neighbours door and give them a brief explanation about your low power air rifle, and how safe it is, and allow them to come for a demonstration of what you do in your garden, plink safely into a safe backstop, hardly disrupting the peace, or whatever it is their kicking off about..
in a nice way ofcourse..
if they decline or get arsey, or dont understand, or just plain dont want you shooting in the garden, then dig up as much dirt you can on them, like you said, drug dealing wifebeaters an all that...
or just tell them your staff is act
