Does a probation condition that imposes limitations on a person's constitutional rights need to be closely tailored to the purpose of the probation condition?

" (Grayned v. City of Rockford (1972) 408 U.S. 104, 109 [92 S.Ct. 2294], fn. omitted.) On the other hand, "[c]ondemned to the use of words, we can never expect mathematical certainty from our language." (Id. at p. 110, fn. omitted.)
