JOURNALISM PROF. JOSEPH CAMPBELL: Slow to learn: Lesson for journos in Brian Ross’ egregious error on ABC.

Brian Ross’ appalling error linking the Tea Party movement to the suspected Batman-movie shooter in Colorado demonstrates anew how slow journalists can be in grasping an elementary lesson of disaster coverage: Resist temptation to report more than you can immediately verify.

In the hours just after a disaster, journalists tend to be especially prone to error and imprecision, as Ross, the chief investigative correspondents for ABC News, amply demonstrated in declaring today on Good Morning America:

“There is a Jim Holmes of Aurora, Colorado, page on the Tea Party site as well, talking about him joining the Tea Party last year.

“Now, we don’t know if this is the same Jim Holmes,” Ross added, “but it is a Jim Holmes of Aurora, Colo.”

The suspect arrested in the shootings early today at a movie theater in Aurora, Colorado, is named James Holmes. But he is not the “Jim Holmes” to whom Ross referred, and the suspected killer has no known connections to the grassroots Tea Party movement, which advocates restraints in government spending. . . . Whatever the reason, his error on a television program that attracts 4.5 million viewers was inexcusable — and eminently preventable.

In the swirling uncertainty that invariably marks the hours after a disaster, journalists are well-served to show deliberation and restraint, to be mindful that error and distortion often blight the first reports of dramatic events.

Plus, the emptiness of ABC’s apology.
