You're wrong. Multiple eyewitnesses who were in the crowd posted their accounts and they agree with each other: It was definitely a crowd crush event. The fact that the crowd eventually parted to reveal the dead bodies gives no indication of what the conditions were like when the injuries were sustained. The video doesn't show what you say it shows. Convulsion is consistent with brain damage due to lack of oxygen. If you watch the videos I linked you'll get an idea how such crowd crush events can happen. You'll never find me in such a big crowd.
