You can blame all accidents on some form of regulatory failure. What I said is that the recent increase in the fatalities is attributable to 3 accidents. Hardly
The telltale signs as Dick points out are a creeping increase in the accident rate.
Dick wasn't asking for the global view he was looking at a specific time period. You were the only one who thought that the global view was necessary and proceeded to state the bleeding obvious that systemic issues are present when complex systems fail.
