Berkeley struggles to keep guns out of schools

Jill Tucker:

On the morning of March 21, shortly after school began, a Berkeley High School student snuck into a bathroom stall with a gun to show it to a friend.
Suddenly the weapon fired, the bullet ripping through the bathroom’s thin outer wall and across a busy downtown street. Had the boys been facing the other direction, the bullet would have flown into a classroom full of students.
No one was injured, but it was the fifth gun discovered at the district’s two high schools since January, a cluster of incidents that has sent parents into a panic and district administrators scrambling to address the new and disturbing trend.
The presence of guns on campus is not just Berkeley’s problem.
According to state and national surveys, 6 percent of high school students say they have brought a gun to school at least once. That’s the equivalent of at least 210 guns at Berkeley High School with its enrollment of 3,500 students.
