tl;dr: if you map audio from the various videos of the Charlie Kirk shooting with the speed of sound, the gunshot doesn't seem to come from the rooftop.
I had been refraining form getting in to this mostly because I was worried that it would be a huge time sink with no real payoff (it's not like I'm going to change anything), but it really seems hard to demy that there is some funny business here.
Here's a 18 minute video I found that goes into it a bit.
It's hard not to feel like the people who are most in to discussing the weirdness if the case gain a lot by playing it up.
I'm curious how others feel about this.
