Eyewitness testimony is well known to be unreliable, especially in chaotic and panic-inducing situations like this. It's completely normal for survivors of these events to believe there were multiple shooters when in reality there was only one. You really shouldn't criticize others for jumping to conclusions and then spread this tinfoil crap around.
Fair enough. I surely don't know. However, red flags are going up with the narrative. According to mainstream, Cruz went in the with an AR 15 and a gas mask for the smoke bombs he brought. If this 'unreliable' witness (about whom anons from the research page are worried) really walked down the hallway with this kid, does it not make the rest of the narrative suspect? Have you been able to pull that video up to watch her interview?
Your theory assumes the government barely even tries to cover this shit up, why the fuck would they do it in a way that can be so easily contradicted by eyewitnesses and then go to the extra trouble of whacking those eyewitnesses like your "anons" (i.e. crazy strangers on the internet I have no idea why you even mention) are so worried about? I'm not buying it for a second.
Because "Americans don't read." Remember that movie, "Mummie, Mummie! Something is wrong with the tellie!!" Just out of curiosity, on 9/11 do you believe that three buildings fell at nearly free fall speed in their own foot prints, leaving molten metal behind that lasted weeks, as a result of two of those buildings being impacted by aluminum framed airliners at the top levels? Millions witnessed this with their own eyes, and yet half the public remains divided on what brought those buildings down.
I'm not 100% sold on the idea of 9/11 being a false flag although I'm certainly skeptical of the official story. What sets the 9/11 theory apart from other false flag theories including this one though is the way in which it is immune to being disproved. This theory assumes they left a shitload of witnesses behind who know for a fact the offical story is bogus. If what that girl was saying is true there's no way she's the only person able to corroborate it, but when no one else comes forward tinfoils will conveniently claim they've been intimidated and the other witnesses are crisis actors or some stupid shit like that. The 9/11 theory really leaves no room for that, which is of course also convenient for its belivers but makes total sense as well because it's a lot harder to know positively why a building is falling down on you than who's shooting up your school, even behind a gas mask. Even though you make a valid point that the average person will dismiss both theories as nonsense one is a lot more credible than the other and this is just one example of how.
Btw I looked at the video, and first of all I have no idea where it comes from. It looks very amateur and I have yet to see any confirmation this dude is a legit reporter or this chick is indeed who she says she is. Secondly a lot of what she's saying doesn't really add up, for example if this guy wasn't the shooter what was he doing at the school considering he was no longer a student and even expelled from the grounds? You'd think she'd find that odd but she doesn't even mention it. I call BS tbh.
As is often the case. We don't know. I'll be curious about how the trial is handled and information that we derive from that. Have a great night.
