Up to now, national parks have been full of people who are not experienced campers and have never seen a wild animal up close. Now the parks will have these same inexperienced people roaming around carrying guns to fight off imagined dangers. The likely outcome will be a lot of dead animals and once in a while, a dead hiker who some gun toting newbie mistakes for a bear and opens up on with something like that assault pistol one of you likes so much.

This scenario isn't so far fetched. I can think of at least one instance where a teen age hunter killed a hiker with a hunting rifle-it happened in Washington. We had a thread on this a while back, but I think it disappeared when the site was upgraded. The kid's excuse was that he thought he was shooting at a bear.

These instances may be rare, but if you're the person who gets shot, that really doesn't matter.

Here's another example--
