The Supreme Court ruled Monday that states can limit privileges of sex offenders who won't admit to crimes as part of therapy.   The 5-4 ruling could spawn similar efforts in other states.  Inmates, who want to keep their privileges, may be forced into therapy and be required to admit past wrongdoing that could be use in future prosecutions.  Convicted rapist Robert Lile argued that the state violated his Fifth Amendment right against self-incrimination n 1994 when it decided to punish him for refusing to sign paperwork admitting guilt in the crime he was convicted of and refusing to fill out a form that listed his sexual history, including names of any other victims.  Among the privileges that now may be taken from Lile are rights to visitors, personal television, and work and recreation.
