A man who once visited the rifle club which also counted as a member the New Zealand mass shooting suspect says he warned police about the shocking and extremist views of members there years ago, but nothing was done.

Pete Breidahl, a New Zealand Army veteran, says he went to the Bruce Rifle Club outside the town of Dunedin once for a serviceman's rifle match hosted by the club, and was horrified by what he saw. Discussions among members there about zombie apocalypses as well as rifles used for combat and "homicidal fantasies" were enough to make Briedahl concerned about the mental stability of those members -- and report what he heard to an arms officer with local police.

"You gotta do something about the Bruce Rifle Club, those people are not f---ing right," Breidahl said he told the officer in a video live-streamed to Facebook. He added that he also met the accused shooter, who Fox News is choosing not to name, that murdered 50 Muslims at two mosques on Friday. But police officers reportedly did not take Briedahl seriously.
