We've been down this technology-gone-amok road before. In 2005, the operator of a Texas-based captive hunting facility developed an Internet-hunting capability, where a "hunter" could go online, spot an animal with a remote-controlled camera, and then shoot the quarry with a remote-controlled firearm. It was a bizarre and frightening example of innovative technologies being used for evil purposes. I didn't think canned hunting could get any worse, until someone sought to layer Internet hunting on top of it. In that case, The HSUS -- and some of our strongest adversaries in the hunting community -- worked to ban this pay-per-view killing in 40 states. (Some of those state bans, which forbid remote-assisted forms of hunting, might forbid using drones, too.)
I am not surprised by the opportunists who would use drones to make the odds even more lopsided in favor of the hunter. Now some hunters employ laser rangefinders, thermal night-vision cameras for hunting at dawn or dusk, motion detectors, GPS trackers for dogs, sophisticated ATVs for the toughest terrain, and much more.
