You're in high school and you bring along a gun to school. Fine. That's just plain commonsense.

But in the first grade? Crazy! And that's just what happened at Cleveland Elementary School in the Excelsior District on Monday. According to the playground rumor mill, the kid was packing heat in his backpack. Turns out the gossip was true. School district spokeswoman Gentle Blythe clains that "the student said he thought it was a fake gun."

While now on suspension, the wee one was released to his parents, not expelled (yet), and no charges were filed against him or his parents. But the case, according to the Gate, has been "referred to the county's Child Protective Services."

This incident comes on the heels of Thursday's arrest of a 17-year-old boy who (allegedly) brought in a loaded semiautomatic gun to night classes at Lowell High School. Oh yeah, and the Gate goes on to report that "28 percent believe it is sometimes or always acceptable to bring a gun to school." Scary.
