 The photo that Ron Livingston (Donnie Anderson) holds of his "dad"  is actually the real life LAPD SWAT officer Donnie Anderson who was  one of the 3 SWAT officers who engaged the final suspect and whom  Ron Livingstons character is loosely based on. You can also see him  and other officers being awarded the LAPD Medal for Valour for their  part in the ordeal at the end of the film.
