The treads did not run her over, merely the front blade.
Here is a good video that replays the scene.
I have seen the actual footage which is why I am so sure of how she died.
I am trying to find it again.
The video you linked is a bunch of different clips spliced together.
It does not show the bulldozer running over Corrie, it shows her lying on the ground afterward.
Thanks for the propaganda link. /s There is no “actual footage” of Corrie’s death, so best of luck “trying to find” something that doesn’t exist. BTW, I hope you’re also aware that the series of photos crafted by ISM and flogged to Reuters, purporting to show that the ‘dozer driver was aware of her presence, was later shown to be a carefully arranged fraud, as the photos which were alleged to have been taken moments before she died were in fact taken hours earlier that day. Reuters did finally acknowledge the fraud and remove the photos, but not until the “news” had flashed all over the world. The left has had more than a century of practice at ‘managing’ the media — don’t be fooled by their lies.
