The carnage at Columbine High on April 20, 1999, prompted a swift and aggressive response around the U.S.
Hundreds of millions of dollars flooded into schools after two seniors stalked the halls of Columbine in trench coats, killing 12 students and a teacher before committing suicide in the school library.
The money -- federal, state and local -- bought metal detectors, security cameras and elaborate emergency-response plans. It put 6,300 police officers on campuses and trained students to handle bullying and manage anger.
Ten years later, the money is drying up. The primary pot of federal grants has been cut by a third, a loss of $145 million. The Justice Department has scrapped the cops in schools program, once budgeted at $180 million a year. States are slashing spending, too, or allowing districts to buy textbooks with funds once set aside for security measures.
Money is so tight that the Colorado district that includes Columbine High, which reopened four months after the shootings, has canceled its annual violence-prevention convention. Miami can afford to send just half as many students as it used to through anger-management training. Many educators and security consultants find the cutbacks frightening.
