National Geographic photographer arrested for feedlot overflight

I would like to know by what mechanism a powered parachute flight over a feed lot might result in humans consuming unsafe food. Presuming mad cow disease inducing "pellets" even could be produced, the pilot could have dumped some over the feed lot. However, this would be an absurdly complex mechanism of distribution and one with a high likelihood of future arrest. Does the feed lot allow inbound grain to be shipped in trucks without sealed covers? I could keep going, of course.

What's bothersome to me is that those using their coziness with law enforcement to dominate their "enemies" don't even feel the need to contrive plausible justifications for their bullying. This is how far America has come.

"After all, hundreds of thousands of cattle are fattening in a 100-mile radius around Garden City and such incidents could turn into a food security issue - especially in an era where agri-terrorism is a threat."

The only agri-terrorist incident I've heard of was The Breeders in the 80s. The California government surrendered to them and the conflict was resolved [1]. Is this era of agri-terrorism the years since 1989 or is it a brand new fantasy threat?
