I think the term "legally blind" is kind of key here. Some people who are legally blind still have some working vision. I am sure there are folks who are vision impaired to the extent of being "legally blind" that would still enjoy the experience of hunting, and it is certainly prudent to require a sighted person to be with them. I think the other key point is that they are simply allowing the use of laser type sighting devices for these legally blind hunters(only).
I'm really touchy about anything that is, or could be, unsafe; anything that is unsporting, or anything that gives hunting a bad reputation. I think that if the (required) sighted people in this case are responsible and safe, it might be a reasonable way to open up more opportunities for sight impaired people. Perhaps the sighted person person should be required to have training, a hunter's safety card or some other qualification as in many states. There should be some qualification for the sighted person. (Wouldn't want an 8 yr. old or totally unqualified person doing the sighted persons role!) You can't take lightly the need to positively identify the target and what is behind it. No guesswork allowed!! Recently a 51 year old guy killed a man and his dog at 60-70 yards while deer hunting in a state park near my house.
I guess I can see issues on both sides of this proposal.
Also, if this were abused in any way, it could be extremely dangerous - so, I would impose extremely stiff penalties for any violations relating to this (proposed) regulation, and in addition to better qualifications for participants.
I'd support anything that will help handicapped people to hunt - as long as it can be done with good sportsmanship and safely. I think the proposal needs a lot more details and definition, but may have possibilities if done right and not abused.
