Michael Nagler is exactly right in his commentary on “Beyond Ferguson”.
Without getting at the root cause of such brutal incidents, the traumas and tragedies will never go away. Focusing on the details of one incident or another as if a legal investigation would reveal some sort of truth is like rearranging deck chairs on the Titanic. Also, an essential part of getting at the root cause is “the shift from a thing-oriented society to a person-oriented society,” as Nagler quotes Martin Luther King, Jr., as saying with regard to the Vietnam War.
Violence, militarism, and materialism, I believe, are a consequence of our cultural worldview of separation, fear, and thus the need for protection from one another (and from nature, as well, by the way). On the contrary, the best protection is connection, not separation.
