Klein was a former producer of Logan's at "60 Minutes," and is now executive director of the Global Reporting Centre and a professor at the University of British Columbia.
"My phone and inbox have been overflowing with questions from friends, colleagues and strangers, asking if Lara was always this way. Let me set the record straight: no," Klein wrote in The Globe and Mail on December 3.
"It's true that Lara tried to push the envelope sometimes, but there's a system in place at reputable news organizations that keeps journalists in check," Klein added.
"The Lara I worked with was a good reporter. She was brave and curious, she listened during interviews and she knew how to tell a good story. While she did her share of pieces that glorified the US military, she was also open to critiques, as in our 2007 story Dissension in the Ranks, which looked at service members refusing to redeploy to Iraq over their concerns about how the war was being run by the Bush administration."
