Watch the video again. The strobe continues to flash even when there is no shots being fired.
I never said it was from a fire alarm, and neither did the officer that reported it on the scanner recording, he only pointed out that it was a strobe light and not muzzle flashes.
How do you tell from a distance, and inside a room what the cause is?
Was someone having a disco party?
Strobe lights in a building are generally from a fire alarm system, and that is what has been posited here earlier.
The acoustics of the area will have an effect on what is heard,and how it is heard, including sound shadows where sound is not heard.
so what was one single solitary strobe light doing on in one single solitary room in a hotel?
