PRETORIA, South Africa -- An expert witness for the defence at the murder trial of Oscar Pistorius was supposed to help the athletes assertion that he killed his girlfriend by mistake last year, but he ended his testimony on Thursday amid blistering attacks on his credibility by a prosecutor who accused him of slipshod analysis and fuzzy explanations. Discount Jerseys China . Roger Dixon, a former forensic scientist for the South African police, was frequently on the back foot as he tried to fend off sharp questions from chief prosecutor Gerrie Nel, who says Pistorius is lying and fatally shot Steenkamp on purpose after a nighttime argument in his home. For nearly a week, the double-amputee runner was subjected to the same kind of harsh scrutiny when he testified that fear led him to fire four shots through a toilet door at what he thought was an intruder. Legal analysts say Judge Thokozile Masipa will review the mass of testimony in its totality, which is said to be almost 2,000 pages so far, and that it can be misleading to assess the course of the trial by a single witness. Defence lawyer Barry Roux, for example, hounded police witnesses with questions about alleged mishandling of evidence at the house where Pistorius killed Steenkamp in the early hours of Feb. 14, 2013. Masipa, who will deliver a verdict on the premeditated murder charge against Pistorius, adjourned the trial until May 5. Dixon, now a geologist at the University of Pretoria, was forced to acknowledge Wednesday that he had no expertise in light and sound measurement, as well as pathology and ballistics, despite his commenting on those topics while testifying about the circumstances of Steenkamps death. On Thursday, Nel resumed his attack, criticizing Dixons work after the geologist did not use Pistorius exact height when standing on his stumps. The prosecutor questioned why his measurements were 20 centimetres (eight inches) shorter in a test to see if Pistorius head and body would have been high enough to be seen by a neighbour through a window of his bathroom. "It is something I omitted. I overlooked it at the time," Dixon said, adding that he was not trying to "mislead" the court. Nel also questioned Dixons statement that he conducted tests showing that Pistorius bedroom is very dark at night and with the curtains closed, a conclusion that would support the athletes contention that his inability to see his girlfriend on the night that he killed her contributed to the shooting. Nel noted that Dixon judged how dark it was without using any light-measuring equipment. "What one can see using your eyes is a very subjective thing," Nel said. "I wanted to see what I could see," Dixon replied. "A measurement doesnt translate to me into what Im actually seeing." Nel also said Dixon was giving convoluted responses, addressing the judge: "My lady, may I just ask the witness which question hes answering at the moment?" Another time, Dixon picked up a prosthetic leg of Pistorius that had been included as trial evidence while discussing varnish traces that he said were found on the prosthesis and he matched to the door varnish. The defence has cited that as proof that the Paralympic champion tried to kick down the door to get to Steenkamp after realizing, according to his version, he had shot her by mistake. Then the prosecutor chided Dixon for not bringing the varnish sample to court. Dixon appeared serene throughout the rough-and-tumble of his cross-examination. Asked if he knew the states case and other trial details, he said: "I am not like most people. I do not have a television set. I do not have a radio at home." His Twitter handle reads: "I am a mineralogist and forensic scientist, I grow clivias and other plants, have a landrover and a Trans Am. I live in a forest I planted myself." He acknowledged the pressure from the feisty prosecutor in a message on his Facebook account that was apparently posted on Thursday morning. He confirmed its authenticity when questioned by journalists. It read: "Third day in court today. Lets see how much of my credibility, integrity and professional reputation is destroyed. It is difficult to get belief in those who will not listen because it is not what they want to hear. After that, beer!" Discount Jerseys Custom . Osasunas Alvaro Cejudo drove the ball onto the crossbar in the fifth minute and his team squandered several long-range strikes before he was denied one-on-one by goalkeeper Jaime Jimenez in the 50th.

NEW YORK -- Phil Jackson is back in New York, providing the Knicks stability, championship-building ideas and a link to the franchises best days. Now they need him to get some good players. Jackson was introduced Tuesday as team president of the Knicks, in the midst of another difficult season and with no easy path to a quick fix. But Jackson has won here before, done plenty of it since and says a couple of years off have left him ready to take on what might be his toughest challenge, turning this dysfunctional franchise into a champion again. "It would be a capstone on the remarkable career that Ive had," Jackson said. Jackson was a member of the Knicks title teams in 1970 and 1973, and they havent won since. He went on to win 11 championships with the Los Angeles Lakers and Chicago Bulls. This will be his first time as an executive and the Knicks say he will be in charge of all basketball decisions. Madison Square Garden chairman James Dolan said he "willingly and gratefully" is stepping back to give Jackson the power to make the changes. "Phil has a vision for the Knicks that I know will put us on the path for success," Dolan said. Steve Mills will remain general manager. "I think that we have a teamwork situation here thats going to be really quite swift and capable of making some important changes as we move forward," Jackson said. The Knicks announced the hiring in the lobby of Madison Square Garden, with a giant "Welcome Home Phil" sign overhead and racks of his old No. 18 jersey on sale. He signed a five-year contract that reportedly will pay at least $12 million annually. After living in California for many years, Jackson said he would spend significant time in New York, starting with Wednesdays game against Indiana. Hes got big decisions coming up involving Carmelo Anthony and coach Mike Woodson. Its the second reorganization in six months for the Knicks, who fired GM Glen Grunwald days before the start of training camp. Mills replaced him even though he had no previous experience running the basketball side. The deal began to take shape at a holiday party hosted by a mutual friend of Jackson and Dolan. Though Jackson quickly declined interest in coaching, they agreed to keep talking. It will be tough for Jackson to makke big changes quickly in New York, where the Knicks face with the salary cap problems. Discount Jerseys League. Amare Stoudemire, Tyson Chandler and Andrea Bargnani will all be in the final year of expensive contracts, making them difficult to unload. And they traded their first-round pick to Denver in 2011 to acquire Anthony. Jackson alluded to that, saying the Knicks "were going to have to go out and work the bushes for players this next year." But he has a vision for how he wants to do it, a change from the Knicks way of too frequently adding big-name players who dont fit any particular style. Jackson said he wont insist that the Knicks run the triangle offence that worked so well for him with Michael Jordan and Scottie Pippen, then Kobe Bryant and Shaquille ONeal. But he made it clear he believes in the systems principles of passing, movement and teamwork. But its not just Xs and Os that have doomed the Knicks during a mostly disastrous decade. Its the policies of Dolan, who has too often involved himself in basketball decisions. Jackson said he will be accessible and will focus on things such as "how players are treated" and "the kind of culture thats built." "This organization has suffered in the past few years from things I think have just been created, by press, by lack of continuity, by lack of solidarity." It wasnt like that when Jackson played in New York. Those teams not only thrived on the court but were well-known and well-liked around the city, players such as Willis Reed, Walt Frazier, Bill Bradley and Dave DeBusschere. "This is the best place to play basketball," Jackson said. Jackson is marrying the daughter of late Lakers owner Jerry Buss and said he will continue to spend time in California, where his children and grandchildren live. Jackson said he didnt know how much day-to-day work he would handle. After five knee and hip surgeries, Jackson is "not easily able to move around" on commercial airlines or scouting at small gyms. That ruled out coaching, the job that Knicks would have loved him to do. But the work needed from the front office might ultimately be more important. "Now to come back to where Ive started in basketball, its a great feeling," Jackson said. ' ' '
