My take on this is that they just had to draw a line in the sand somewhere, anywhere, to try to keep the technology advances from ruining the sport. I think that more importantly much of this is to help with the general non-hunting public's perception. If hunters are perceived to have an unfair advantage it plays into the hands of the anti-hunters. The rules make sense to me for B&C's purposes.
It does seem shortsighted that the Kansas restrictions apply to non-game species such as coyotes. I think we all will have to live with increasing restrictions whether they make any sense or not, and it will get worse quickly if folks push the envelope with what they can do instead of what they should do.
