First, on Wednesday, a 14 year-old boy shot two students and two teacher and then shot himself at a school in Cleveland.
Now, CNN is reporting the arrest of another 14 year-old boy in Pennsylvania suspected of planning a "Columbine type event" at a high school.
Police in Plymouth Township near Philadelphia took the boy into custody after a search of his home turned up a number of weapons, including a 9 mm rifle with a laser scope and dozens of air guns.
Police also found an operational hand grenade, three other hand grenades in the process of construction, bomb-making equipment and manuals.
Rest of the story.
These two incidents beg some obvious questions. How safe do you feel at your schools? Do you think they take adequate security measures (resource officers, metal detectors, etc.)? Is there something more schools can do help stop the violence?
