Badgering the Badger Hunters

It is not only the case that the 'culling' of badgers in the UK to 'protect dairy cattle from bovine TB' is unsupported by science (there's a clue in the name of the disease) but it seems that the cull is a) expensive and b) may involve considerable animal cruelty (https://www.theguardian.com/environment/2018/sep/30/covert-footage-reveals-cruelty-of-badger-culls). One can't help but feel that the cull is largely carried out because farmers are a powerful lobby group in many rural areas?
