“I’m willing to look at any evidence they might have, but i’m not willing to simply accept witness testimony that they heard two shooters, because it’s so easy to be mistaken about this when you are surrounded by buildings that can cause echos.”

I guess it would depend on how much weight a person would put on the observations of those who would have experience with guns and especially those who’ve been trained to keep their heads when there’s gunfire going on.
Also, there are some videos being posited as showing another shooter - those should also be addressed by the PTB.
I saw a video that showed flashes coming out of the Fourth Floor, and people thought they were gunshots. I've read reports that the flashes turned out to be a strobe light, and of course no windows on the 4th floor were broken.
If some good evidence emerges of a second shooter, i'll believe there is a second shooter, but at this point I think such speculation is just the result of people wanting to believe in conspiracies.
