Whenever you have a camera close to something dangerous , you have to have an extra guy ready to pull the operator out of the way , since the cameraman is focused only on what 's directly in front of the lens . " Do they ever actually have to pull them away ? " I ask . " Not often , " he replied , " but it 's good to be safe . " So , this truck that 's supposed to topple over on its side ?

Why might a camera person be yanked from their spot ?
To save them from an out of control accident .
