One comment regarding it’s authenticity as coming from the hand of the El Paso Walmart shooter: Does the so-called manifesto accurately identify the weapon and ammunition used?
To answer your questions this was not, in my opinion, written by the shooter
I read all the way through it and the nature of it, terminology and vocabulary to me put to lie that this was his work alone if at all. I note where the colloquialism Y’all is thrown in occasionally but not consistently. Having lived in Texas in the area (Allen) 11 hours from El Paso where I have also spent a lot of time I find these inconsistencies an indicator of taking someone else’s work and modifying it to give it “flavor”. Last in his “manifesto” he talks about being killed and this being a one way trip yet he was wearing eye and ear protection as if he was at a shooting range. Note that the Columbine attackers as most if not all the others wore such gear, it was truly a suicide mission. I believe he knew that he would not die and he was apprehended in the parking lot attempting to merely drive away when his car was blocked by 2 police vehicles and no further gunfire occurred.
As to the AR-a5 vs AK 47 he seemed to favor the AK but was looking for fragmentation (internal wound damage mentioned) as well as overheating more typical of the AK Vs AR weapon.
I have looked into this extensively and there are several reports of multiple shooters and they were there not repeating what they had heard elsewhere. This then answers the question of how many bullets he had to shoot and the number of people hit. He had a single 30 shot clip on his weapon and no additional ones so mathematically it is impossible given all of the dynamics as well as moving targets for a single clip to effect 52 wounded or dead
Also the MSM changed the original picture of him day 1 to a different one that does not resemble him day 2. Further, immediately post the even 3 others were arrested/detained and then released
With the supposed timing of the manifesto’s uploading, I’m wondering if there wasn’t an ‘advisor” inciting from the wings who wanted to see if he’d actually go before pushing the button.
