Donald Moskowitz: We need oversight of classified documents

To the editor:

The Massachusetts Air National Guardsman who posted highly classified documents on social media should not have received a top-secret security clearance or any security clearance based on his terrible background. He discussed violence and murder and use of an assassination van on social media. He also looked up mass shootings and government standoffs on his government computer. He was suspended from high school for discussing use of Molotov cocktails and other weapons and making racial threats.
