wow...so every black bear in sight is killed to find the ONE....3 extra bears were killed... you call yourselves Biologists or wildlife managers.... surely not all bears were equal in size, height, weight etc. you must have had a pretty good description from several witnesses and you could not narrow it down????... my oh my...maybe you should be demoted to desk jobs or not have a job in this field at all. 
I do agree the necessity to find and kill THE attacker bear, as an injured bear is even a more dangerous bear...but this...this just stinks of ulterior desires and fears and giving in to perceived demands from higher ups etc.
