Years ago in Lansing, Michigan, some PETA higher-ups did a presentation in which they gave out lists of all the restaurants that serve meat, the banks that hold their mortgages, and the facilities that house live animals (regardless of whether it's for research, food, or pet sale purpose), and then had a class on how to create a gasoline bomb in a milk carton. They weren't charged because as long as the bomb class follows without context from talking about places they want to see destroyed, they're not actually advocating violence. I'm sure the same argument would apply here...
Anyway, any context on that tree image? I mean, obviously even if the chemtrail theory were true it couldn't do that, but it does look like a fairly specific event.
Edit: Actually, Google image search was better at finding it than I thought:
