Accusations that NYPD brass deleted or failed to preserve e-mails that would have been evidence in a class-action lawsuit are ridiculous because then-Commissioner Ray Kelly ruled the department almost exclusively in person and over the telephone and his second in command, Joseph Esposito, didn’t like e-mail and used the computer in his office solely “to display a continuous montage of family photos,” court papers state.

Kelly and Esposito revealed their Luddite habits in depositions after the city was accused of destroying or failing to turn over e-mails relevant to a 2010 class-action lawsuit over summons quotas.

Lawyers for the plaintiffs in the summons case said in a July letter that it was “untenable” that Kelly and Esposito didn’t write any e-mails using terms like “summons.”

“I ran the department via virtually constant in-person meetings, not by electronic means,” Kelly said in a deposition Friday.

Esposito also didn’t use e-mail — mostly because he didn’t like it.

“I have no qualms admitting that I am not technologically savvy,” Esposito said in a deposition.

“While there was a computer in my office, I used it to display a continuous montage of family photos,” he explained.
