to be clear, i don't think there's anything wrong with any of that
that being said, every mass murder/terrorist attack/whatever is going to lead to conflicting reports and conflicting eyewitness accounts, neither of which is some sort of smoking gun or even particularly relevant in the grand scheme
That's also one of the things that fuels these types of fires. People are always going to accuse the official story of being manufactured to explain away those inconvenient things that they didn't want getting out that did.
For everything that you want to explain away as bad eyewitness accounts, other people aren't so readily able to just shrug it off the shoulders.
It's just the nature of the beast.
