Staten Island DA Dan Donovan appeared on “Good Day NY” this morning and explained why he had decided to support a bill signed into law by Gov. David Paterson to prevent the NYPD from keeping information gleaned from stop-and-frisks that don’t result in any charges.

Donovan insisted his position, which is in keeping with his five would-be Democratic AG opponents but against Mayor Bloomberg and NYPD Commissioner Ray Kelly, wasn’t a politically motivated attempt to woo moderate voters in an increasingly blue state, saying it has “nothing to do with my race for attorney general.”

“I just think our whole government is based on less intrusive government on people’s rights,” he said (starting at about the 3:30-minute mark in the video that appears below).

“The individuals we’re talking about were stopped, there was a determination made that they weren’t committing a crime or about to commit a crime, there’s no actual legitimate reason why government should retain their personal information.”

Donovan called stop-and-frisks a “useful tool for fighting crime” and said he doesn’t agree with the allegation that the practice is overused or disproportionately targets minorities, saying each instance has to be judged on its own merits.
