Another shooting in blue-collar Santee, California, and another in a parochial school in the Williamsport, Pennsylvania, bring school violence back into the news. Though media coverage exaggerates school violence, both safety and education demand “preventive” measures that will not increase violence. There is no educational problem that policy cannot worsen.

Every preventive or punitive action is an instructional method that teaches someone something. Because we do not think of safety measures as lesson plans, we seldom evaluate whether the intended consequence is achieved, and we are unaware of unintended results. After Columbine, the most common actions were patently ill-conceived and the unintended learning was more than schools can take in the present political climate.

U.S. policy in Iraq, as reported in the mainstream news, amounts to “we liberated Kuwait” and Saddam “kills his own people.” Saddam Hussein has been so vilified that when we think of Iraq, we fail to think about the millions of Iraqis who unfortunately have no more control over the actions of their dictatorship government than we have over our “democracy.” The mainstream media plays almost exclusively to our fears of “weapons of mass destruction.” With rare exception, the suffering of the Iraqi people is largely an untold story in the U.S. The Gulf War and the sanctions imposed on Iraq for the last 10 years have caused the deaths of over 1.5 million people in a once thriving country of about 22.5 million people. Many people, including the former U.N. Humanitarian Coordinator for Iraq , Denis Halliday, call this genocide. The sanctions themselves have become the new weapon of mass destruction.

I still remember the shock of May 4, 1970 after hearing the news of the shootings at Kent State – the unnerving feeling that they were coming for me and my friends next -- as a Detroit 9th grade hippie greaser/MC5 listener/White Panther Party supporter. My rage grew in high school fueled in part by Crosby, Stills, Nash & Young.

When the Ameritrade company launched a $200 million marketing drive to explain the joys of online trading in autumn 1999, a barrage of TV commercials invited viewers to join in the fun. The news was bullish, and the firm's motto -- "Believe in yourself" -- provided an upbeat message. Tech stocks led advances in self-affirmation.

A senior vice president at Ameritrade proclaimed that online investing "empowers individuals to take control of their financial lives." Within several months, the Nasdaq composite index nearly doubled. When spring 2000 began, plenty of satisfied new customers were glad to be playing the click-and-invest game.

Now, four seasons later, the Nasdaq is less than half of where it was. Losses have been particularly devastating for many of the investors who'd found the get-with-it advertisements and other media hype too irresistible to resist a year ago.

It's not easy to look at ourselves as others might see us. For a country, the need is especially acute in times of international crisis -- but that's when nationalism and other reflexive biases are most likely to become pivotal.

One of the ways to test for media slant is to put the shoe on the other foot. A big story this month provides an opportunity for inquiry in the world of intense media spin.

Here are some excerpts from actual U.S. news coverage, with only one type of change -- I've reversed the references to China and the United States. The mirror-image narrative is worth pondering.

ABC World News Tonight: "There are concerns about national security and a Chinese military flight crew that was forced to make an emergency landing during a surveillance flight along the East Coast of the United States. The Chinese spy plane was equipped with sophisticated intelligence-gathering technology."

CNN: "Chinese military officials say that they are, first and foremost, concerned about the safety of the crew. They want that crew returned back to China."
