 Notably, the shooter's location was outside the security perimeter, raising questions about both the size of the perimeter and efforts to sweep and secure the American Glass Research Building, and how the shooter was able to obtain rooftop access. Well, I always wondered, how did he get the weapon in? Then they said he was walking around with it. Then I thought, I don't know, was it already there planted? Did he have something going on in this building? Did he plant it somewhere outside of the building? Did he bury it outside of the building?
