Ferguson remains unconvinced, saying such schemes are "only tolerable when necessary, and only permissible when they work". Obtaining his approval is crucial to the conspirators, although Farrington proceeds to organize two shooting teams in anticipation that Ferguson will change his mind. One of the teams is shown during practice in the Mojave Desert, shooting moving targets at medium-to-long range. One of the shooters says that he can only guarantee the operation's success if he fires at a target moving below 15 miles per hour.
