Information from video cameras, a close relationship with police and years of work to bolster safety measures kept a man with a gun out of a Jewish school and helped officers find him after he fired shots outside the building, a Jewish security organization said Tuesday. A man tried to enter Margolin Hebrew Academy-Feinstone Yeshiva of the South in Memphis, Tennessee, on Monday afternoon but was denied entrance into the building, Memphis police said. The man, whose identity has not been released, fired several shots and then left in a maroon pickup truck, Assistant Police Chief Don Crowe said.
