Vehicle plows into crowd on Bourbon St., with 14 fatalities

She said, and I quote, "This is not a terrorist event." She announced prematurely that it was not terrorism. She didn't wait to declare or classify anything accurately. She got it 100% wrong, and did so prematurely. She made a mistake, or was given bad information, but let's not act like she and/or the FBI had all her/their ducks in a row.
I don't know what press conference you watched but she came out of the gate and explicitly said they were investigating this as a possible terror attack and then later said the ISIS flag was located on the trailer hitch of the vehicle & they were working to determine the subjects potential associations and affiliations with terrorist organizations....but go off I guess.
