We know of over 20 survivors of Walder’s decades-long rampage of rape. With all the secrecy that surrounds abuse, that means there are probably hundreds of victims. There is no way it could have gone on for so long with so many victims without many others helping to suppress the truth. Even allowing for those survivors who never told anyone else, there will have been plenty of others who went to rabbonim, dayanim, therapists, relatives, and friends. The reporters at Haaretz were not the first to discover this scandal. They were just the first to publicly expose it. Calling Walder a rasha and removing his books does nothing to solve the problem of the cover up.
About twenty years ago the Orhthodox Union (OU) was also hit with a newspaper (The NY Jewish Week) revealing serial sex abuse by Rabbi Boruch Lanner a leader in their NCSY youth movement. They responded by commissioning an outside investigation. They then released enough of the report to confirm that Lanner abused many children and that many complaints by victims were ignored by the leadership of NCSY. Some heads rolled. Not enough was revealed and not enough heads rolled. But still, this was a dramatic step forward for a frum organization. Nothing resembling this in the slightest is happening in the Haredi world.
As sure as the sun rises in the east, we can all be sure that all the brouhaha and denunciations of Walder as a rasha will not cost anyone their position for covering up his abuse, though some may pay a price for inept PR execution. And that means leaders can go on covering up with impunity. The only change is that they now know that if Haaretz catches wind of a scandal they have to make the offender walk the plank while the enablers can cruise on happily to yet another cover up.
