Police are duty-bound to say "don't take the law into your own hands" when a gun is involved.
But the frustration of farmers who boxed in a suspected sheep thief at the weekend is understandable.
The rural grapevine swung into action on Saturday when two men were spotted with a dead sheep.
Let's assume they didn't have permission to take it, in the dark.
Stupidly, the two men had placed themselves in a situation where they were on a road that could be boxed in at each end.
