Then why did you bother posting? Or do you have disinterested factual evidence that shows that such interactions must end with a dead person?
Given your track record of blind faith underlying most of your assertions, it is no surprise that you don't even understand that their is an option between taking an unsupported absolutist position and taking and equally absolutist opposing position. I posted because I think claims ought to be commensurate with a rational evaluation of the evidence. ksen's claim logically presumes that the cop's acted recklessly and shot the guy even though it did nothing to reduce the threat that either he or his bull posed to anyone. Nothing in the story supports that conclusion, and what information we do have contradicts it, especially combined with basic general facts of human behavior I already mentioned.
These make the odd's are overwhelming that the owner was threatening the cops if they shot the Bull, and if the Bull was charging people, then every second they waited for another solution put others lives in danger from the Bull. There is no plausible motive for the cops to want to shoot the Bull if it wasn't a threat, and many witnesses that would contradict any false claims that it was. The only alternative scenario to the owner threatening the cops (and thus inherently threatening the lives of everyone endangered by his Bull) would be that the owner walked onto the scene with his gun and intended to shoot the Bull if needed, but the cops just shot him when they saw the gun. Given that the owner was called to the scene by the police dispatcher and thus the cops knew he was coming, that is not very plausible either.
