“The Best for the Group comes when everyone in the group does what's best for himself AND the group.”

Context: When an individual wishes to stand in opposition to authority, he does best to find support for his position from others in his group. The mutual support provided by men for each other is the strongest bulwark we have against the excesses of authority. (Not that the group is always on the right side of the issue. Lynch mobs and groups of predatory hoodlums remind us that groups may be vicious in the influence they exert.)

Context: Every officer has accepted a calling that sets them apart. Most of us imagine, if the moment called for it, that we would risk our lives to protect a spouse or a child. Those wearing the uniform assume that risk for the safety of strangers. They and their families share the unspoken knowledge that each new day can bring new dangers. But none of us were prepared – or could be prepared – for an ambush by hatred and malice. The shock of this evil still has not faded. At times, it seems like the forces pulling us apart are stronger than the forces binding us together. Argument turns too easily into animosity. Disagreement escalates too quickly into dehumanization. Too often we judge other groups by their worst examples, while judging ourselves by our best intentions. And this has strained our bonds of understanding and common purpose. But Americans, I think, have a great advantage. To renew our unity, we only need to remember our values. We have never been held together by blood or background. We are bound by things of the spirit – by shared commitments to common ideals.
