"The moment any person comes to accept as justifiable an act of violence upon another — whether physical, spiritual or otherwise — that person has already lost the moral battle, even if he is currently winning the somatic one."

My comment: Several years ago I gave a ski lesson to a retired English policeman. He told me that in over twenty years he never drew his gun.
What kind of society are we that police in any given U.S. city draw their guns more often than this Brit did in twenty years as a municipal police officer.
