A pretty jarring story out of Washington state, where an 11-year-old boy was last night arrested and faces an attempted murder charge following the police discovery of a handgun, more than 400 rounds of ammunition, and several knives at a Vancouver, Wash., middle school. No one was hurt in the incident, which prompted a two-hour lockdown at the middle school and an elementary school next door yesterday morning, the Columbian reports. The boy has been placed in juvenile detention, CNN reports.
