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. Cheap Jerseys Free Shipping . 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!"

Miikka Kiprusoff had just announced his retirement after a decade-long run in Calgary and it would be up to Berra and Ramo to fill the void. BEREA, Ohio -- Michael Sam was laughing with teammates as they conducted a running-back drill for kids, each youngster stiff-arming and juking his way to a touchdown celebration dance in a makeshift end zone. Sam didnt stand out. He was just another rookie, simply one of the guys. The NFLs first openly gay active player, Sams first months in the league have gone just as he would have hoped. "Its very positive, its very fun," Sam said. "Im excited to be playing for the Rams, Im excited to be in the NFL." Sam was in town with the other NFC rookies, who took part in a PLAY 60 youth football clinic with local children at the Browns training complex, part of the leagues four-day rookie symposium. The AFC rookies will begin their symposium on Wednesday. The full orientation for the players includes presentations, workshops and speakers covering a broad range of topics that fit under four core teaching principles: NFL History, Total Wellness, Professional Experience and, yes, Workplace Conduct. But workplace conduct -- that is, experiencing workplace respect and maintaining positive relationships, two main outlined elements of the symposium -- hasnt been a problem for Sam. Not with his teammates and not among the other rookies. Its obvious he has the respect of those around him. "You dont see anyone not talking to him or against him," said guard Greg Robinson, Sams teammate in St. Louis and the second overall pick in Aprils draft. "They look at him as a football player." That doesnt mean Sam has to shy away from who he is, though. In a group meeting during the symposium, he was able to share some thoughts on his own life with teammates and rookies from the Tampa Bay Buccaneers. "Just know someones story before you judge them. Thats pretty much what it comes down to," said Tampa Bay wide receiver Mike Evans. "Hes a normal guy, just like us. NFL Jerseys China. Just here to play football." Sam is also quickly becoming known for his sense of humour. "The Rams love him," Evans said. "They always joke around with him. He seems like a fun-loving guy." And like any rookie, he is adjusting to the stark contrasts between the college and professional game. Sam was the SECs Co-Defensive Player Of The Year last season and was taken with the 249th overall pick in the seventh round of the draft, but he is working hard to carve out a role on a loaded Rams defensive line, led by ends Chris Long and Robert Quinn, who was second in the NFL in sacks last season. He has also been finding work on special teams. "Its every fast. Everything is full speed," Sam said. "If you make a mistake, it could cost you that win in practice or that win in a game. That one mistake. So youve got to pay attention to details." As for the details that have followed Sam around since he came out to the media in February, they havent mattered to anyone in the league, especially those who have met him. "Hes just another guy in the locker room," Robinson said. "Hes really cool once you get to know him and I feel like he has a great story behind him." That story has resulted in a whirlwind year for Sam, without much time to reflect on the fact that he is finally an NFL player. Its a lifelong goal that made him not unlike every player on the field Tuesday, having fun with kids eager to show off their quick feet or sure hands. "It still hasnt hit me yet, its still like a dream," Sam said. And as he continues to cross through uncharted territory, there is still that one vital, important thing to keep in mind. The thing that truly makes Sams experience a worthwhile success. "They treat me like a rookie," he said.
