 It is not unusual for a terrorism suspect to plead guilty to the charges against him/her, especially if (s)he is placed in solitary confinement pre-trial; such isolated prisoners want nothing more than to end the solitary, and will plead out to end it.Isolation can also destroy the prisoner’s ability to work with his lawyers, as well as his ability to testify on his own behalf at trial.Under the Geneva Conventions, it is illegal to hold a prisoner in solitary confinement for more than 30 days.
