As Stephen Kessler writes (February 22, 2015) “Cops are human and flawed like everyone else and so they sometimes make fatal mistakes.” That raises the question: does law enforcement as a career attract people with built-in prejudices and tendencies toward the need to control certain segments of society, indeed to regard some people as the enemy? This attitude could very well underlie the widespread gulf between police and community in too many parts of the country, and that, in turn, would suggest that the most important part of any police chief’s job is to identify those individuals on the force who harbor the “them against us” attitude and help them find another line of work.
