The defense's position weakened when, on November 28, Darrow was accused of orchestrating to bribe a prospective juror. The juror reported the offer to police, who set up a sting and observed the defense team's chief investigator, Bert Franklin, delivering $4,000 to the juror two blocks away from Darrow's office. After making payment, Franklin walked one block in the direction of Darrow's office before being arrested right in front of Darrow himself, who had just walked to that very intersection after receiving a phone call in his office. With Darrow himself on the verge of being discredited, the defense's hope for a simple plea agreement ended. On December 1, 1911, the McNamara brothers changed their pleas to guilty, in open court. The plea bargain Darrow helped arrange earned John fifteen years and James life imprisonment. Despite sparing the brothers the death penalty, Darrow was accused by many in organized labor of selling the movement out.
