Look at this video which is showing some convincing evidence of another shooter at a lower level also a shooter in the crowed. Also none of the debunkers have taken on the audio analysis that have been done showing that there are to locations for the shots. Based on timing differences between the muzzle sound and the sound of bullets hitting hard objects down below. I will be adding another video that is very convincing in regards to the audio analysis of the shots being fired.
