Well done Drache, your actions are a credit and an example to us all.
I wouldn't be so quick to condemn the fellow who wounded the bear. In BC, its legal to hunt black bears with a .22 centerfire. Sometimes animals are wounded and get away, and a black bear can disappear quickly in any kind of cover. There might not have been much of a blood trail initially due to the small bullet entrance, but sometimes even major caliber bullets make what appears to be a small entrance wound. We frankly don't know if the hunter who wounded the bear made an effort to follow it up, but I hope he did.
