Here's a more complete statement of the case against Hamilton CAS. The biological parents did not ask that the children be told the Easter Bunny is real, and the foster parents appear to have been very reasonable. If the facts as stated here are accurate the foster parents are in the right whether you are a Christian, atheist or pagan, or a reasonable Easter Bunny.
