I pondered the same thing. Being in a drug-induced stupor and sheer stupidity doesn’t even fully explain leaving laptops with highly sensitive, illegal, national security info on it.
Hunter has been a “deep state” player for the last 25 years. He absolutely knows what’s at stake.
Hunter may have been in the game for over 2 decades, but his cognitive abilities are probably not what they once were. Heavy drug use over that period would take its toll. Clouded judgment and even as one other mentioned... blackouts.
