Not the answer i was looking for, but i may have been looking too deep into it.
Its all about knowing if your in the right and where you stand.
For example: you turn up at your permission which holds canada geese which you can get a clear shot at with your .177 SMK from behind a shed at 30 yds away. However to your rear there is a public footpath, regularly frequented by the red sock brigade, say some yds away?
Or an overlooking obnoxious neighbour?
You pop off the goose with a superb head shot with your airgun, it drops to the floor and has a good old nerve fla
