The sound for Rescue 2's siren is that of a Federal 'Q' model siren, but Rescue 2 is obviously not equipped with a 'Q' siren, as a 'Q' siren is a model that is too large to mount under the hood and isn't mounted anywhere else on Rescue 2.
The initial call for Rescue 2 to the schooner rescue incident is made with three SCU tones, when there is only Rescue 2 responding and therefore should only be one SCU tone.
One of the shooter's weapons was an M1911A1 .45 caliber pistol. He uses it in the manager's office to shoot him once. He then goes to his room, and when the police come, he fires 8 times through the door, for a total of 9 rounds. The magazine in the weapon only holds 7 rounds. Even with a round in the chamber, this is more rounds than the weapon will hold.
