That works too, but if the officers are following their training, then that is not where the problem lies. If the departments are TRAINING police to do this, then you have to go after the departments.
Given the number of officers who are using the “I feel threatened” excuse nationwide, I think it’s safe to say that they are following their training-—at least in claiming to feel threatened whether their victim is man or beast.
A presumably adult human being is responsible for their actions regardless of training.
the SS and the KGB were also following their training- an excuse so far beyond lame as to be criminal.
