I think your logic is slightly biased. If the LEO has position himself to prevent your escape and you try to escape by removing the LEO forcefully, then you are at fault no matter what. Disobeying a lawful order given to you by a LEO is a breaking the law. Whether he attempted to kill the LEO is immaterial since he made the effort to escape and by doing so, endangering the LEO. If the LEO feel that he is in danger, he can terminate that danger any way he see fits. And his fellow LEOs can aid him on that enterprise. Either way, your logic is flawed because you think that he has that right to escape. (LEO stands for law enforcement officer(s).) Proper thing for this gentleman to do was simply surrender and throw himself at the mercy of the court. How simple, eh?
