Likewise, their goal is to stop logging, not endanger the lumberjack with a spike. So I suppose they take all precautions to notify people that the trees have been spiked - by placing posters, notifying authorities, etc.
That’s like saying a bombing isn't terrorism if you call in a threat.
I'm all for preserving our forests, and most people who say we have lots left haven't got out of their cars while in the forest. Go 100 yds off the road in most of the national forest and you hit logged out areas with trees less than 40 yr. old, it's a neat trick where they leave unharvested corridors along the road so you don't see it unless you hunt or hike. But spiking trees should be charged as attempted murder.
The end does not justify the means.
