Yeah, not once he mentions the location of the recording device in his little analysis. The simple calculation from lag time to distance traveled by the bullet is only valid if the recording device was at the point where the bullet hit the pavement or very close. If the recording device was not there it's all wrong.
Imagine the recording device half way between the shooter and the point of impact. The sound of the muffler travels only half the distance, while the sound of the impact also travels half the distance (back). As an extreme, if the recording device is close to the shooter, you'd hear the sound of the muffler before the sound of the bullet hitting the pavement, so this guy's conclusion would be that a second shooter is shooting standing on the pavement, shooting down into the pavement so the bullets bounce and fly back into the barrel of the other guy's gun.
