Fox News (excerpts):  Yellowstone National Park, WYO - Yellowstone National Park authorities will not try to capture a female grizzly that killed a back country hiker because the bruin was trying to defend its cubs when it was surprised by the man, a spokesman said Thursday.  The mauling of Brian Matayoshi, 57, of Torrence, CA, was a purely defensive act, park spokesman Al Nash said.  He added that Yellowstone typically does not try to capture or remove a bear in what he called a "wildlife incident."  It was the first fatal grizzly attack inside the park in 25 years - but the third in the Yellowstone region in just over a year.  The attack occurred on Wednesday about 1 1/2 miles up a popular backcountry trail and not far from an area that is one of the park's top attractions.  Busloads of tourists normally gather there to take in the view from  iconic Artist Point.  Matayoshi's wife, Marilyn, escaped serious injury and no longer was at Yellowstone Park, officials said.  They declined to reveal her whereabouts.  Nash said the couple saw the bear twice on their hike.  The first time, they continued hiking.  The second time, the grizzly charged them and Matayoshi told his wife to run.  She called 911 on her cell phone, and other hikers in the area responded to their cries for help.  The woman told park officials she didn't see the bear attack her husband.  When the bear went for her, Nash said, she dropped to the ground.  The grizzly lifted her off the ground by the day pack she was wearing and then dropped her.  Marilyn Matayoshi may have had scrapes and bruises but didn't seek medical attention.  Her husband died at the scene, Nash said.  "We observed both bite marks and claw marks," he said.  In this case, Nash said, park officials relied on Marilyn Matayoshi's account of the attack in deciding not to pursue the grizzly.  She told rescuers that the couple surprised the sow with her cubs - one of the most dangerous situations possible for humans encountering grizzlies.  Based on her account and understanding of grizzly behavior, rangers believe the bear instinctively charged to protect her young.  The bear had never been documented before, never been tagged and there was no reason to believe it had interacted with humans before, Nash said.  If so, the decision may very well have been different.  
 
My Comments:  Imagine this happening to your husband, wife, or God forbid, one of your children.  I can't even fathom what this man's family must be going through.  His wife could have also been killed, but she was blessed to escape alive.  I think that it is absurd for a national park to allow people to hike where bears frequent.  Average people, you and me, have no idea of the risks involved; obviously if we did, we wouldn't go near.  I looked up Yellowstone bear warning signs on the internet.  Most of them are very mild warnings, such as a sign with a bear on it that says, "Bears frequent here."  Another posts a warnings, but mild warnings in my opinion.  People are prone to think, How dangerous can it be if I'm allowed to come in here."  Honestly, is it ever worth risking anyone's life, ever, by letting people hike where bears frequent the park?  Even if it's one person in 25 years, isn't that one person's life valuable enough to keep people away from park areas where bears frequent?  Actually, three deaths have occurred in about the last year in the regional area of Yellowstone.  A lot of money goes into grizzly bear research and elitists have an agenda to increase the bear and wildlife population throughout the world, in their endeavor to restore the world to an "Eden type environment."  They have increased the bear populations 75% deliberately for this reason.  In fact, I assure you that the bears are more important to these people than human life.  The Word of God tells us that in the last days, vicious animals will attack more people, "I looked, and there a pale horse and the name of him who sat on the horse was Death, and hell followed with him.  Power was given to them over one-fourth part of the earth to kill with the sword, hunger, death and by the beasts of the earth" Revelation 6:8.
