CTH had stated that the police had fired thousands of rounds.
You will notice that the "thousands of rounds" is in quotation marks. Use of quotation marks tells the reader that the writer is simply passing along what others may have said.
Relying on my memory here, I believe a witness may have been quoted as such in the early aftermath. Regardless it was obviously hyperbole as a modicum of common sense would ascertain.
Anything else?
