Redirecting Ukrainian drones

NATO and the EU accuse the Putin forces of redirecting Ukrainian drones and sending them over Finland, Estonia, Latvia and Lithuania. I don't see any sense in the resignation of Latvia's prime minister over this. The right thing to do is to develop a net deployer which can get a drone tangled and bring it down. (Ukraine's army has had success defending against Putin forces drones with used fishnets.) This might make it possible to study what the Putin forces had done to take control of the drone. Suitable encryption, with redundancy and error detection, could make that impossible. It is much more difficult than mere jamming.
