Boston ( CNN ) -- A federal jury Monday saw a rare display of emotion from reputed mob kingpin James `` Whitey '' Bulger when he laughed while reveling in his former drug dealer 's nostalgia as the dealer testified in his federal murder trial . Jurors also saw the family of a man shot to death , allegedly by Bulger , react to disgraced former FBI supervisor 's tearful public apology for his role in two 1982 deaths . Former FBI agent John Morris apologized in court to the family of Michael Donahue , whom Bulger is charged with killing , for leaking sensitive information that eventually made its way to the reputed South Boston crime boss , and according to testimony , cost Donahue his life . `` I do n't ask for your forgiveness , but I do want to express my sincere apology for things I may have done and things I did n't do , '' Morris said to the Donahue family . Michael Donahue 's three sons and widow , Patricia , sat front row in the reserved section in the Boston courtroom . Bulger is charged with killing 19 people during what prosecutors allege was a nearly 20-year reign of terror in South Boston . Morris admitted telling his `` best friend , '' Bulger 's disgraced , now-jailed FBI informant handler John Connolly , the identity of another informant who had agreed to cooperate with the government against Bulger regarding the 1981 slaying of a wealthy Oklahoma businessman . Bulger faces off with FBI agent who went from pal to prosecution . According to previous testimony from Bulger 's former associate and partner John Martorano , Bulger rained bullets on Donahue 's car in pursuit of drug dealer Brian Halloran to prevent Halloran from implicating Bulger and his crew in the killing . Donahue , who was not affiliated with the gang , was giving Halloran a ride home from a bar that night . He was shot to death in May 1982 . `` Not a day in my life has gone by I have n't thought about this . Not a day in my life that I do n't pray that God give you a blessing and comfort for the pain that you suffered , '' Morris continued while looking directly at Donahue 's widow . `` I am truly sorry ; I do not ask for forgiveness . That 's too much , '' Morris concluded in a trembling voice as tears began to well up in his eyes . Tommy Donahue , one of Donahue 's sons , and his mother returned Morris ' gaze . Outside of court , Tommy Donahue said Morris can `` take his apology and shove it . His tears and his apologies do n't mean crap to me and my family , not one bit . '' During the court break , Tommy Donahue exchanged kind words with the man defending his father 's accused murderer , defense attorney Hank Brennan . Brennan elicited the apology from Morris when he pointed to the Donahue family in court and asked Morris if he has ever apologized to the `` families left behind '' due to his `` inappropriate actions . '' Bulger trial opens window on mob world of cold violence , fierce loyalty . Donahue described his family 's `` lousy predicament . '' `` We want Bulger to go to jail , but we have to rely on Whitey Bulger 's lawyers to give us the truth . The government is n't going to give it to us , '' he said . `` It 's a double-edged sword . '' Patricia Donahue , who spoke for the first time since the trial began , said about Morris ' apology Monday : `` No , those words did n't mean anything to me . I think he probably really feels guilty ; to me that 's a good punishment because that is something he has to live with for the rest of his life , '' When court returned after a brief recess , Bulger began cracking up , his shoulders moving aggressively up and down , when his former drug dealing associate Joseph Tower started telling a story about the time Bulger , or `` Boots , '' saved Tower 's brother 's life . Tower is testifying under an immunity agreement and was called to the stand to explain Bulger 's extortion business , or `` rent . '' Bulger is also charged with extortion , racketeering and money laundering . Tower , former cocaine dealer , said he entered into a business agreement with Bulger , reluctantly admitting that Bulger got a piece of the earnings , in exchange for `` protection . '' `` I said , now you are in serious trouble , '' Tower testified he told the gangsters who kidnapped his brother , alluding to his affiliation with Bulger and how the kidnappers had made a dangerous mistake . Bulger got the kidnappers to release Tower 's brother after a money exchange gone wrong , Tower said . When the judge called a sidebar , the two old friends exchanged shoulder shrugs , head nods and brief smiles . Tower will return to the stand for cross-examination Tuesday . Why we ca n't get enough of the gangster life .
