As an addendum to Patrick's post, the following are just a handful of other convicted terrorists currently held in Florence, Colorado:

Zacarias Moussaoui, Conspirator in the September 11, 2001 attacks
Omar Abdel-Rahman, "The Blind Sheik"; involved in 1993 WTC bombing
Richard Colvin Reid, Islamic terrorist, nicknamed the "Shoe Bomber"
Wadih el-Hage, Conspirator in the 1998 US embassy bombings
Mahmud Abouhalima, Islamic Mujahideen leader, 1993 WTC bombing
Jose Padilla, Convicted of aiding terrorists
Mohammed A. Salameh, 1993 WTC bombing

In fact, Salameh (along with Mohammed Saleh and Victor Alvarez, convicted in a separate plot to bomb several targets in NYC) had spent many years in Leavenworth, specifically the federal penitentiary.  So did Thomas Silverstein, who the BBC once called "America's most dangerous prisoner."  Furthermore, Padilla had spent time in the Charleston brig, where another "enemy combatant," Ali Saleh Kahlah al-Marri, currently resides.  As far as the prison on Ft. Leavenworth, serial killer Ronald Gray has spent the last 20 years there.  Also, during World War II, 14 German prisoners of war were transferred to the USDB after killing their fellow inmates.
