I first heard the words "complacency precedes disaster" from my brother, who is a commercial airline pilot. When I asked him about it, he explained that industry experience was that no amount of training or education could would stop people from making simple errors with profound consequences when things get routine, guards are dropped and safety protocols are ignored. While a crash, either actual or narrowly avoided, will sharpen folks' attention, their level of care and attention will inevitably begin to wane after a while. Then bad things will happen. It's the same for us lawyers. From what I hear, it's epidemic right now.
