Trump shot?

[ArMaP]

Then why do the first 3 shots lack echoes, and the 5 shots that come seconds later do not?

The first 3 shots do not lack echoes, in fact, they have a lot of echo.

Watch the video below and tell me what you think, do the shots from the first group sound like the shots the second or not? Does the sound waves of both groups look similar or not?

One thing I found strange when looking at the sound waves was that the second group appears to have a shot doesn't appear to have an echo, around 1:01 on the video below.



To help the comparison, here are the images of the three groups.

First group.



Second group.



Last shot, the one I think was fired by the counter-snipper team to kill the shooter.




PS: The sound was taken from the video at https://www.itemfix.com/v?t=9048fs
I used Audacity for the visualisation of the sound waves.
