Donald W. Cook is a Los Angeles attorney with decades of experience bringing lawsuits over police dog bites — and mostly losing. He blames what he calls "The Rin Tin Tin Effect" — juries think of police dogs as noble, and have trouble visualizing how violent they can be during an arrest.

Any American who pays attention to law enforcement has heard of the strategies: "broken windows," "stop and frisk," "zero tolerance." These are all variations on what's broadly known as "proactive policing": efforts to seek out and prevent the causes of crime before it happens, as opposed to a more reactive policy of just sending police when called.

MARY LOUISE KELLY, HOST:

A controversial alt-right political rally planned for San Francisco on Saturday afternoon has been canceled. Organizers announced the decision Friday afternoon, saying hostility from local politicians and leftist activists made the situation too dangerous. But concerns about protests on both sides linger, so the police remain on alert.
