PRETORIA, South Africa -- Oscar Pistorius fired guns in public in the months before he killed his girlfriend -- once out of a car sunroof on a road and once in a crowded restaurant, a onetime friend said at the athletes murder trial Tuesday, drawing an aggressive effort from the chief defence lawyer to pick holes in his testimony. The account by Darren Fresco portrayed Pistorius as a reckless hothead infatuated with firearms and seemingly drifting down a precarious path before he fatally shot Reeva Steenkamp through a closed toilet door at his home before dawn on Feb. 14, 2013. Frescos description of how Pistorius once berated a police officer fit the prosecutions attempts to cast the double-amputee athlete as prone to flashes of anger and blinded by an inflated sense of entitlement at a time when his public image was that of a clean-cut poster boy for overcoming adversity. "I said to him, are you (expletive) mad?" Fresco testified after, he said, Pistorius fired his gun out of the sunroof of the car later on the same day that he had the dispute with the police officer. "He just laughed." At the same time, the testimony was coming from a man whose own actions were under scrutiny. Judge Thokozile Masipa cautioned Fresco, who was also a friend of Steenkamp, that some questions could incriminate him for offences including discharge of a firearm in a built-up area, negligent damage to property and reckless endangerment. She said he would not be prosecuted if he answered the questions truthfully. Pistorius, 27, denies shooting the gun in the car, although now two witnesses say that he did. The athlete is on trial for murder in the killing of Steenkamp, and also faces two firearm charges for shooting in public and a third firearm charge for illegal possession of ammunition. Pistorius says he shot Steenkamp by mistake, thinking she was a dangerous intruder. The prosecution says he killed her after an argument. The athletes demeanour in court Tuesday was drastically different from the previous day, when he needed a vomit bucket as he heard a pathologist give graphic details of the injuries he inflicted on his girlfriend when he shot her multiple times. This time, Pistorius mostly sat with his hands in his lap and often made notes. Fresco testified that Pistorius altercation with a police officer happened in late 2012, when their car was pulled over by traffic police for the second time that day. He said Pistorius was furious with an officer for handling his gun, which he had left on the passenger seat. "You cant just touch another mans gun," Pistorius said to the officer, according to Fresco. "He started telling the officer: Now your fingerprints are all over my gun, so if something happens, you are then going to be liable for anything that had happened. He was furious about that. Someone else had touched his gun." Fresco and a former Pistorius girlfriend have both testified that the Olympian shot his gun out of the car sunroof later that day. But their stories do not match in parts, a fact highlighted by defence lawyer Barry Roux. Fresco, who said he was driving the car, testified that Pistorius fired without warning sometime after visiting an unidentified persons house. Samantha Taylor, who was dating the athlete at the time and was in the car, has testified that it happened soon after the altercation with police and after Pistorius and Fresco discussed finding a traffic light to shoot at. Roux also questioned Fresco about an incident at a packed Johannesburg restaurant in the posh Melrose Arch district in early 2013 -- about a month before Steenkamps death -- when he said he handed his gun under the table to Pistorius and it fired. According to Fresco, Pistorius said there was too much "media hype" around him and asked Fresco to take the blame for the shooting, which he did. Fresco said he had warned Pistorius that the gun was "one-up," meaning it had a bullet in the chamber. "I knew that he had a big love for weapons," Fresco testified. "My assumption was that he had competency." Roux asked Fresco when exactly he had warned Pistorius that there was a magazine in the gun and a bullet in the chamber, and when Pistorius had asked him to take the rap. The friend couldnt pinpoint the precise times. "Will you agree, Mr. Fresco, you have uncertainty ... about what specifically happened and what was said?" Roux asked. Roux sought to undermine Frescos character, questioning why he crumpled up a speeding ticket and threw it on the floor of the car after he and Pistorius were stopped by the police. Fresco also said hed been following some previous testimony in the case on Twitter, which witnesses should not do. If convicted on the murder charge, Pistorius could be sent to prison for at least 25 years before the chance of parole, the minimum time someone must serve if given a life sentence in South Africa. The judge will ultimately deliver the verdict and decide on any sentence. South Africa has no trial by jury.

The Habs general manager maintained that the teams success over the last three months are due in large part to special teams and the play of goaltender Carey Price. The Canadiens star goaltender struggled in the latter part of last season and Bergevin brought in former Chicago Blackhawks colleague Stephane Waite as goaltending coach to help get him back on the right track. "Carey has been our most valuable player this year," he told reporters during the teams morning skate in Philadelphia. "All the credit goes to him for his comeback. Hes come to work whenever he goes on the ice. He is playing great hockey and is one of the reasons why we are in our current position." Price and teammate P.K. Subban were both named to Canadas Olympic mens hockey team on Tuesday, joining six other Canadiens representing their countries in Sochi. Bergevin would not comment on the status of contract negotiations with Subban (a restricted free agent with arbitration rights this summer), but had plenty of praise for the young blueliner. "I dont want to discuss (the talks) publicly," he said. "Two years ago, he (Subban) was sometimes a healthy scratch. His progression has been huge and hes not finished." Bergevin also addressed questions regarding veteran forwarrd Daniel Briere, who has struggled in his first season with the Canadiens.dddddddddddd Briere, whos been the subject of trade speculation over the last week, has impressed both the GM and head coach Michel Therrien with his recent play - including a three-point performance against Ottawa on Saturday. "I never got wind of it," said Bergevin when asked of any possible rift between Briere and Therrien. "Daniel has faced difficulties, but hes on the right track. Hes played much better hockey for some time." And if Briere needs to look anywhere for some added inspiration, he doesnt need to look further than his own dressing room. "David Desharnais has had a difficult start to the season," said Bergevin. "And hes been one of our top players now for a long time." Bergevin, who had a first-hand look at some of the teams prospects at the World Junior Hockey Championship in Sweden, also likes he sees for the future, particularly forward Jacob De la Rose whom he hopes will play in North America next season. "On the whole, our prospects performed well," he said. "All six players got a lot of ice time. I was especially impressed with (Jacob De la Rose), who is a big guy who did very well for Sweden. Also, Martin Reway, whos a lot smaller physically, had a great deal of success as well. They had key roles on their teams on such an important stage. The future looks promising for our kids." ' ' '
