Yes, she was anti-American, leftist instigator and apparently thought she was capable of stopping a bulldozer so complete was her brainwashing. And es, this is what happens if you throw yourself in front of a huge machine like that.

Very disturbed individual. Her death is unfortunate as apparently she wasn't mentally sound. Her family should have kept her home and got help for her. If you jump in front of a bull dozer, or a bullet or whatever lethal force is there, the end results are pretty easy to see in advance. And it certainly doesn't make one a martyr. Just dead.
