In 1889, after several days of rain, a badly maintained dam broke in Johnstown, PA. The deluge destroyed the town and killed 2,209 people. No one blames the rain.

In 1912, the Titanic collided with an iceberg and sank drowning more than 1,500 people. The Titanic had ignored heavy ice warnings and had too few lifeboats. No one blames the iceberg.

In 2005, poorly built levees broke in New Orleans and at least 1,500 died. Levees.org will say “mission accomplished” when, with regard to the catastrophic flooding during Katrina, no one blames the hurricane.
