The Dome was designated a "Last Resort Refuge." The term was defined in the official LA emergency plan differently than what you, the media, the people who went there and common sense would think it meant. On this, alas, they followed the plan. Details at my post upthread here.

#1 The idea that the plan had no provision for a levee-breach contingency is ludicrous.
#2 The idea that NO ONE ELSE (upon reading the plan) was able to make the observation in #1 is profoundly surreal.
