Las Vegas police and Clark County firefighters experienced numerous communication problems and failed to follow some protocols on the night of the Oct. 1 mass shooting, according to a federal report released Monday.

But the 61-page report also described the response to the attack — which left 58 concertgoers dead and more than 800 people injured — as “efficient” and “coordinated,” crediting the counter-terrorism training of Las Vegas police.

The Federal Emergency Management Agency created the report with participation from the Metropolitan Police Department and the Clark County Fire Department. It took nearly a year to complete and includes 72 lessons learned, the Review-Journal reports.
