Some of the comments here on hunting make me wonder about people.
In a perfect world, every shot is a 10X and an instant kill
Targets and game animals present themselves for perfect no error involved shooting.
The light doesn't go, the wind doesn't blow, the weather is perfect, no snow,rain, or boiling heat, weapons don't missfire and bullets/arrows are not deflected by an unseen branch.
The Game animal fall over dead right there, or if it runs it does so towards your vehicle and then falls over dead.
If you have to track the animal, it will be sure to leave a line of flagging tape and paint arrows on tree's so following it will be easy and it won't find the deepest, thickest, wettest part of the swamp to hide in or won't run up the side of a mountain to fall off a crag and land on a ledge that one has to rappel down to to recover.
All hunting area's are perfectly flat and you can see tommorrow from where you are standing.
Get real people.
I have hunted for over 25 years, I learned to track animals before my dad would even consider allowing me to shoot one (not that he neglected my instruction on that score) I have hunted deer, moose, elk, bear (black and brown) wolves where legal and have spent many a winter trapping.
No matter how GOOD you are, you are interacting with a variable (a wild animal) and while you may have lined up the perfect shot, sometimes the variable decides, for whatever reason, that now is the time to get out of here and very often, it is done with no visible indication to the hunter and spoil that perfect shot placement. Sometimes they refuse to die and while they have absorbed a massive amount of damage, they get away and thru a variety of factors are lost.
Sort of like some people who absorb an unbelievable amount of punishment and still kill,wound,hurt thier attacker (that's another story and thread)
Hunting has no absolutes or garauntee's.
I have tracked animals that were hit solidly, but if one went by the indications on the trail, the animal showed no signs of it, I tracked them as much by getting into the head of the animal as I did by sign and terrain and without bragging I am good at it, but I still have lost animals.
So, before you condem someone, with only a smidgen of information with no hard facts, THINK.
