The line about sufficient force, not to "match," but to overcome, is
very significant.We don't want to encourage excessive force.
There are certainly many instances where police action can be challenged,
especially when they shoot a non-threatening dog, attack the wrong house, use
improper techniques, etc. But at the same time, we don't want
to create an environment where the cops (or any law-abiding citizen defending
him/her-self) is legally required to engage in a "fair fight." Once evil threatens and the "good guy/gal" is in jeopardy of life and
limb, whether its our military, our police, or the citizens, they should be
allowed to win, to prevail, to be the one who goes home.
