Are you sure it was the convention center mentioned those many times and not the superdome? They are not the same place.
Yes, absolutely sure that the Super Dome and the Convention Center are different places - - - the Dome was always said to have some 10,000-25,000 refugees in it, and the Convention Center 5,000 - - - the Convention Center was referenced as the place where murders and rapes were occurring - - - the Dome had shootings, a suicide and rapes, but no murders - - - the Convention Center has been a well known part of the landscape of this situation for days . . .
