Rarely is violence against children as premeditated as the attack that left 15 dead and 24 injured at Columbine High School. More typically, it’s a result of young people without constructive, healthy outlets for upsetting feelings either unleashing stored up emotions inward or outward. Parental messages that urge children not to feel what they feel ("Don't be angry," "Don't be sad," Don't be scared.") often lead youngsters to stop confiding in trusted adults, giving more energy to bottled up feelings that can become destructive. Assuring more children grow up with two parents who are actively engaged in their lives within neighborhoods where caring adults are regularly a positive influence is the most important contribution we can make to a future that's safer for all of our sons and daughters.
