About

During cross-examination, the prosecution used the photograph to show that the Hybrid III test arm weighed 9.38 pounds, compared with O'Keefe's estimated arm weight of 11.86 pounds. The 2.48-pound difference is about 26 percent of the test arm, while the test arm is about 21 percent lighter than the estimate. Brennan argued that the test speeds should be reduced by 26 percent; Wolfe disagreed that the speed must be reduced by 26 percent.
