The dramatic videos of the shooting of Stephon Clark in Sacramento last month have rekindled anger over police shootings of unarmed people, often African-Americans. Many see the Sacramento shooting as a sign that little has changed in the way American police use deadly force, despite years of protests and media attention since the shooting of Michael Brown in Ferguson, Mo., in 2014.

Lately, the NRA has relied heavily on videos to communicate with the public and its supporters, and video is how it announced its position on legislation to temporarily remove guns from people thought to pose a threat.

Investigators are blaming human error for the panic-inducing false missile alert in Hawaii last month. They say it was sent out by a state emergency management worker who mistook an exercise for a real attack.

At the same time, the incident has exposed what may be a more widespread problem: disagreement over whose job it should be to warn the public about missile attacks.

"Why did he even have a gun?" — it's a common refrain in America, often after mass shootings by people who legally aren't supposed to have firearms.

One of the worst recent examples was the massacre in a Sutherland Springs, Texas, church last November, in which 26 people were killed by a man whose domestic violence conviction should have barred him from buying guns.

The jitters over North Korea's missile tests have led Hawaii to bring back air raid sirens. The state already has sirens in place in case of tsunami, but starting this month the state will once again test the "wailing tone" meant specifically to warn of attack.

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.

Seven years ago, a researcher named Lisa Lit published a study that she now calls "a real career-ender."

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.
