GREENSBORO, NC -- Rockingham County sheriff Sam Page watched in disbelief as the Las Vegas horror unfolded on his TV screen.

He saw a situation he trains his deputies for, but hopes they'll never have to encounter. But, he also saw good people risking their lives to save strangers.

"As I started seeing the situation unfold, I also learned we had veterans, we had good citizens out there, we had off-duty officers from out of state and also on-duty officers try to help victims get out of the kill zone…we also had officers moving toward where the active shooter was, trying to stop the threat.”

Page explained his deputies are trained on different active shooter scenarios.

"We also train our citizens on run, hide, fight. We recently talked to our churches, business groups, all our county employees -- 700 county employees -- about what to do. If you see something, say something, so we can get help there as quickly as possible, " Page told WFMY News 2's Good Morning Show Tuesday.

He said in situations like Las Vegas, where first responders arrive when there's still an active threat, the first priority is to stop the shooter.

"Every minute that goes by is a life. We want to stop the threat. But also, when you have people (civilians) available to jump in and help like they can help save lives..."

In the event there's someone shooting from up above, like the Las Vegas gunman shot from the 32nd floor of the Mandalay Bay casino hotel, Page said, "The best thing you can do is get out of the kill zone, hide and conceal yourself, so you're not seen as a target."
