Destroying items is destruction of property, usually that is a crime but its farm from terrorism. Unless you really believe that ceo’s are cowering under their beds in fear because first a gaspump, second must be storming their private islands with guns?
Just like with other laws there are exceptions where something does and does not count as a crime.
Accidentally killing a home invader in self defense isn't murder either.
Obviously i dont know what truly goes on in any judges head but considering that industrialist have been actively involved in covering up how much environmental damage they have actually done to populated areas. (Exploit underground water during times of drought causing cracks and collapses in hundreds of familie homes to give you a single example of something i know happens)
If one considers that i believe there is a good argument agains dismantling the tools of oil companies in the name of self defense.
Industries should not pretend to feel terrorizes by some ecologists and climate conscious youth. The people are getting terrorizing by systemic exploitation of commons for nothing but the greed of a few for ages.
