Here's an idea !
As cattle farmers are subjected to having there cattle tested for TB every year and if found positive the cattle are destroyed.
Now a way that Brian May and his gang could prevent a cull would be:-
Catch and test every badger for TB. If its infected destroy it to prevent further spread. If its clear tag it with a coloured / dated tag and release it.
Next year do the same again and replace the tag with a different colour, like Tax discs on cars.
Now if the badgers don't carry TB (and pigs fly) then Brian May will be happy and we all need to look elsewhere to see why our cattle are becoming affected.
Ok if the badger testing & tagging group fail to test annually then there will be badgers with out of date or no tags displayed. These should be legally shot on sight.
Sounds fair to me.
