BBC reports the Metropolitan Police in London are considering using eagles to bring down drones being used for criminal activity. Aside from the idea being inherently cool, critics do raise concern about the welfare of the birds being used in this way especially given the design of most drones having four rotating blades. The report does not mention how police would discern between drones being used for criminal behaviour or for recreational use. The idea is simply being considered at the moment, but more study is needed and protocols (if deployed) would need to be written as well. Still, a pretty cool idea.
