Received anonymously by activists in Ireland:

Shooters arrived back to their cars today in North County Dublin, Ireland, to find their locks had been superglued and paintwork had been keyed with the initials "ALF". This is the second warning they have received. Next time it will be more than their windows and paintwork that will need replacing.

This is a warning to all you scumbags. "Continue shooting and you will be
a target of the Animal Liberation Front!"
