Like myself, I'm sure many people are perplexed by police violence either to or fro. On the railroad, safety has evolved to where a worker is empowered to refuse service if the task at hand is regarded unsafe by such employee. Safety is first.
As long as police killings of citizens are legal, when police are in pursuit of a suspect or plural regarding a crime, two policemen must be involved. The first must have an electronic megaphone stating repeatedly: "We are the police. Stop and do nothing or you risk being killed dead," in English or Spanish, as the case may be. This shifts police responsibility to the pursued, which is so very confused in today's police activities. Or as such. Safety first!
Also at issue is the incredible delinquency of politicians regarding the current affairs of the British and American closure of Russian diplomatic relations as expulsion of Russian diplomats. An eye for an eye was superseded 2000 years ago and demonstrates how would-be Christians, ain't. This affair and sanctions against any person or nation are the anti-Christ/Satan/Ego in action. Don't you see? If you don't see, you aren't civilized. All too common in our ego-nurtured culture of no peace on earth. Lead by example, not by precedent and the sheep will follow the shepherd as the day follows the night, whether you see or not. This is a promise that no politician will risk taking, due to ignorance, prejudice, superstition, all traits of ego perseverance which dwells in the past of non-learning beatitudes. Presence of mind is the modality of learning, which is the miracle of attention/intention as the living god. Safety first.
