Yes, that is true.  He had no way of knowing another mentally ill person would take a gun to school.  One thing is that the government doesn't seem to have any way to know or enforce anything if you lie on the FFL.  The form does ask about mental illness, but it is just a check in a box.  Same as being convicted of a felony.
