Earth Liberation Front terrorism may be fairly lame when you compare them to the real Islamo-fascist pros, but it would be a mistake not to treat them as a real threat.
The real pros can take advantage of the neworks that the ELF nuts have created. And some of the ELF nuts will be even crazier than the average Vegan loon with explosives knowledge.
Those ultra-loonies will firmly believe that a good hard strike using the real pros to inflict high casualties will finally convince Americans that milk is murder.
