Wouldn't it be safer to have manufacturers of portable devices pass the DO160 requirements?

Well, that's a humorous take on it, but it wouldn't have to be that way. Also, it wouldn't take a scanner for every row. It takes a sensor (antenna) for every few rows (recall we are looking primarily at 108-152 MHz, and that means an antenna of significant length) to get usable sensitivity with a 50 Ohm input scanner). But a lot of sensors could be multiplexed into a single scanner, with the scanner switching between different sensors continuously. When a level in the problem frequency range is registered above some limit, the system would check if that particular signal was at a frequency that was going to be used on that approach or take-off. If not, it is a false alarm and doesn't matter. If the signal frequency is close to that being used by the various comm/nav devices, only then would the crew have to interact with a scofflaw passenger. With this system, it can be made clear that the problem isn't just a bureaucratic snafu, but is a clear and present danger. As in, "Ladies and Gentlemen, in violation of aircraft safety rules, a personal electronic device is a being operated in row 15, and it is interfering with our navigation homing device, which guides the aircraft to a safe landing." We must delay/abort our approach until this device is secured by the crew until the aircraft has safely landed." And "shaming" a passenger by delaying a take-off or landing could be a powerful incentive for both the guilty party to never let it happen to him/her again and the other passengers to resolve that they don't want to it to happen to them, either.
