After reviewing the video several times it appears to me the woman did not knock the Pope down..she was taken down by security personnel before she reached Him.
She never touched the Pope.
Security was on her.
She was taken down about 1 second after jumping the divider it seems. But not sure if she got a grab at the pope or not on her way down. With the security thrust pressing to get to her, it is possible that they knocked down the group like a bowling ball, but the video angle was not conclusive. Looks like we will have 50 more views out soon, everyone was filming this like they almost expected it to happen.
It looked to me like she fell in front of him—probably as a result of security tackling her—and the Pope tripped over her.
It looks to me like she grabbed the crozier on her way down and that’s what pulled him over. He was caught off guard and off balance and probably had his weight on the crozier.
Right at the beginning of Mass! The devil never rests.
I disagree. It looks to me like she was able to grab his arm or, most likely, his garment and held on tight enough so when security tackled her the Pope was pulled down as well.
