[Sentience is not fooled by your weaseling!!] I am aware, or can inform myself of, the abilities and skill level that most inmates currently possess, so I can judge whether or not they would be able to contribute, or if allowing them to help would simply endanger them senselessly.
For those inmates whose psychological evaluations I am familiar with... I might reconsider any volunteers whose profile indicates that they are treacherous or indecisive.
