You have to remember that killing unarmed protesters, especially a nun/pretty girl/etc , would do more damage to the facility through politics than terrorists ever could.
The protesters have been involved in other similar incidents at other federal facilities and each has served time in federal prison.
Walli and Boertje-Obed were convicted of defacing a federal facility and trespassing charges in 2006 at a missile facility in Garrison, N.D. Boertje-Obed was released from prison in 2007, and Walli was released seven months ago in January, according to records.
Rice, a Catholic nun, spent time in prison for actions to close the School of the Americas/WHINSEC at Fort Benning, Ga. She was also convicted of trespassing in the “Creech 14” protest case stemming from a Las Vegas case that targeted Creech Air Force Base and the use of unmanned drones.
