Based on a brief analysis of the audio, it would seem all 3 shots rang out from the sixth floor of the Texas School Book Depository.
It became very clear like 10 minutes later (mostly when the shooter's head left his body) that this was a retarded take and I regret it.
Too easy to make wild and stupid speculations as situations are rapidly developing. Lesson for next time: shut up for a while.
