I cannot say how I know what I know. Rabbonim infinitely bigger than me have assured it. I know they are ok — not great, not magnificent, not terrific. They eat (although not you and I eat in a free society), they have visitors and lawyers helping them. Rumors are ugly things. Is it torture to not have freedom? Then all prisoners are being tortured. Would you not daven for them regardless of their situation — mediocre or bad? Please, please daven for them and the people who are trying to help them.
