That was one mistake Kimble made.
Another, in my opinion, was that the video displayed at least three instances of poor judgment. The first, of course, was Kimble's decision to wear camouflage instead of orange. The second was using the WVU fight song as theme music behind the hunt footage. The third was his post-kill celebration, which included a prolonged war whoop, a "we're No. 1" finger raised skyward alongside the rifle, and his exuberant use of the "Let's Goooo, Mountaineers!" chant.
It was like a wide receiver faking out a cornerback, catching the football, sprinting across the goal line and, instead of celebrating with teammates, turning and spiking the football at the defender's feet.
In short, it was unsportsmanlike conduct.
Naturally, viewers opposed to hunting raised a ruckus. Viewers who support hunting raised a counter-ruckus. The national news media got hold of the story. Reporters contacted WVU administrators for "official comment."
In the end, Kimble drew a mascot's equivalent of a 15-yard penalty. University officials, no doubt a mite miffed that they'd been dragged into a controversy by the school's most high-profile goodwill ambassador, forbade any further hunting with the school's rifle and let it go at that.
Kimble wasn't the first Mountaineer mascot to hunt with the famous muzzleloader. Others had used it to kill deer. As far as I can determine, none of the other mascots got into trouble.
Had it not been for Kimble's lapses in judgment, he wouldn't have either.
One final thought on the subject: If I read another news item that calls the Mountaineer's muzzleloader a "musket," my head might explode. It's a percussion-cap rifle, not a musket. A musket's barrel has a smooth bore. The Mountaineer's has lands and grooves, and is much more accurate.
