An 11-year-old was arrested on Wednesday in Vancouver, Washington after he brought a handgun, over 400 rounds of ammunition, and several knives to school. Frontier Middle School, where the boy attends, was put in lock-down for two hours while police searched the grounds -- but luckily there were no injuries. The arrest comes after a 12-year-old boy shot and killed a teacher in Nevada (and wounded two other students) on Monday, and a 14-year-old boy was charged with murdering a math teacher in Massachusetts on Wednesday.

CNN:

"A Washington state middle school boy was arrested Wednesday and faces an attempted murder charge, after he brought 400 rounds of ammunition, multiple knives and a handgun to his school, police said.

The 11-year-old was booked into a juvenile detention facility after the incident that caused the lockdown of Frontier Middle School, Vancouver Police said."

Police did not say who was allegedly being targeted.

In California, a sheriff's deputy mistakenly thought he saw a teen carrying an assault rifle on a California street on Tuesday and shot him dead.

Over the weekend in North Carolina, a 2-year-old girl fatally shot herself in Fayetteville, and the toddler's father faces involuntary manslaughter charges.

Still no gun control talk in Congress...
