Supermarkets threatened with vandalism in campaign against badger cull But more extreme groups are using the internet to call for illegal action. One campaign, known as "you kill the badgers, we kill the machines" has been suggested on online discussion sites by members claiming to be from the Animal Liberation Front. The activists are threatening to put credit card style gift vouchers and reward cards, "that have been stolen and kept free of dna," covered in superglue into machines. A similar action in 1999 reportedly broke 100 Natwest cash points costing £6,000 each time to fix but no one was convicted. A spokesman for CBAG, the Coalition of Badger Action Groups, that is calling for non-violent action, asked people to boycott all the supermarkets supplying milk from the cull areas. There is a direct link. The milk in those shops has paid for bullets that go into guns that shoot badgers. Sainsbury's, Morrisons and Tesco, who have issued statements appearing to support the cull, are in the firing line. Asda wrote to CBAG in August claiming they are "not in favour of the cull" and have made it clear that "none of our milk is from the West Gloucestershire area" but have failed to issue a clear public statement against the cull. Brian May and the RSPCA have also asked people to boycott milk from cull areas. A coaltion of mainstream groups, Team Badger, are calling on members of the public to write to ministers and supermarkets. CBAG have resorted to more extreme action by encouraging activists to play "badger, badger" songs down the phone to the Department for the Environment, Natural England and other organisations helping to organise the cull. The Secretary of State has obtained a High Court injunction against one website to stop publication of his home address and telephone number to stop such calls. CBAG insist they are against intimidation and damage of private property.
