I agree that calling the idea dumb is counterproductive. The OP asked for feedback and I believe that one of the OP's poll choices was "useless." While I don't think the idea would be useful for most hunters or anybody in LE, I will give him credit for being creative and thinking outside the box. I would not be interested in wearing such a device since it would need some type of metal or glass, etc. for reflectivity to answer the laser inquiry and a vest containing that would likely be hot, noisy and bulky. I'd say cost but most of us already spend a LOT on hunting gear anyway.
