Uh, it seems obvious that the question is not tree trimming in particular but maintenance generally. The gas explosion the killed thirty people might hypothetically have been just an accident but logic, rules-of-thumb and actual evidence available all pointed to it being a problem of inadequate PG&E maintenance. Assuming the cause was a defective power line, maybe it was totally an accident but it seems unlikely in the scheme of things - most likely it was part of their pattern of negligence. Edit: Note, the Camp Fire has bankrupted them. They are bankrupt, in bankruptcy proceedings. They are also on criminal (not civil) probation. None of this stopped their stock from rising after the recent events - where a more naive me might expect their stock holders' money would be forfeit once they reached the level of bankruptcy (unsecured debtors and all).
