Speaking in general terms, based on my 20+ years in law enforcement, I am not surprised that these elders got probation. Just about every criminal defendant in the U.S. gets probation for a Misdemeanor crime, which I believe is what these elders were charged with. It is very rare to get a jail term. Jails are run by the county and funded by the county. The courts are constantly working with elected Sheriff's to keep jail populations down. Prisons are run by and funded by the state. First time convicted felons whose crime is a non-violent felony and whom have no prior criminal history are almost guaranteed to get probation as well in lieu of prison time.
The big win or silver lining on this case is that the elders involved were arrested, charged, tried, and convicted in the one country in the world that boasts having the most religious freedom. This case should put all elders in the U.S. on notice - report child molesters to the police immediately or arrest prosecution yourself! If it happened once it will happen again. This is not a unicorn case.
