Otherwise, if the opponent kicks the human shield, she might be kicked down together with the human shield. If they fell, she would die! Also, her weapon was not just a knife, it could also be a human shield. Because the elevator was too narrow, when the human shield was pushed out, it could knock down a group of people. Before pushing the human shield out, she had to lock down the next human shield. She had to make sure that after she pushed away the human shield in her arms, she could immediately catch another one.
