TIPS FOR MOM AND DAD
Parents and even private citizens with no link to a child can help prevent school shootings, says Peter Langman, a psychologist and the author of Why Kids Kill: Inside the Minds of School Shooters (Palgrave Macmillan). Here are some of his suggestions:
Set limits on your child's privacy. Keep open communication. Know your child's friends, what he does, what websites he visits. If there is a preoccupation with weapons or violent scenarios in journals, he may need help from a counselor.
Pay attention to school warnings. If the school contacts you with concerns about your child's violent stories or class presentations, he may be depressed or enraged and need help. These "red flags" have been noticed by teachers before school shootings, but parents rebuffed school officials.
Eliminate easy access to guns at home.
Recognize possible rehearsals of attacks. Some school shooters have done drawings, animations and videos or written stories in advance that depicted brutal acts.
Stay alert to possible signs of future trouble. Private citizens have foiled rampage killings by youths. Among them: a clerk in a photo shop who noticed photos of a teenager with an arsenal of guns and someone who found a notebook with plans for a high school shooting in a parking lot. If you notice a possible threat, promptly notify the police.
