These things happen,..
I suppose as a hunting man,.you don't want to make a regular habit of it though.
If you take a few terriers and a running dog or two out into the countryside,.it is inevitable that something will occur..Personaly,.I try to avoid 'accidents',.but,.if I am working in the 'set-a-side' for the rabbits,.prior to ferreting or maybe pushing rabbits out of high grass towards a net,..and,.a hare, fox or deer rises,..well,.that is tough luck...If somebody wishes to make a court case out of it,.then so be it,..
INTENT,...that is the word...
All the best,..and do go
