A whistleblower inside the DOE in New York City told me the Bloomberg administration plans to eliminate all emails. I assumed they were reacting to the Indiana scandal, where Tony Bennett’s emails showed that he engaged in grade-fixing and assembling lists of campaign donors.

Maybe yes, maybe no.

But what we learn from this story is that the Bloomberg administration plans to delete emails in many agencies, not just the Department of Education.

The Bloomberg administration could let an important part of its legacy end up in a digital Dumpster.

Currently, the city only has plans to retain the emails of a finite number of agencies from the Bloomberg era — and those are mainly being saved to protect itself in the event of future litigation, DNAinfo New York has learned.

But the city still hasn’t decided whether to preserve the emails of major agencies like the mayor’s office, NYPD, the Department of Education andFDNY, sources said.

If the emails are not saved, an unvarnished window into the decision-making and thoughts of Mayor Michael Bloomberg and top deputies likeSchools Chancellor Dennis Walcott and NYPD Commissioner Raymond Kelly could vanish.

When DNAinfo New York asked the mayor’s office and the city Law Department about the possibility that these agencies’ emails would eventually disappear, both called that account “incorrect and inaccurate” but wouldn’t elaborate.

This is unfortunate, as emails are now the public records that future city officials and historians will need to understand how policy was designed and implemented.

It seems to be akin to burning public records. This should not happen.
