The interesting thing about this story is that drones are now part of activism.
A story is not a story unless you can get video; this feedlot (a mini-scandal in NZ because we're famous for grass-fed, free-range beef but... we don't entirely always do that) has been running since 1991 but it wasn't until activists brought up a drone and took video that suddenly it became a TV story.
