QUESTION: # of terrorist or enemy of state designated US prisoners

question / pregunta: 

How many US prisoners (US citizens held in state or federal cages) are designated as terrorists or enemies of the state? Would also be interested in looking at this over, say, the last fifty years; as even folks with these designations sometimes get out.
