The jury of seven women and five men deliberated for two hours on Wednesday and resumeD their discussions Thursday.
Assistant U.S. Attorney Joseph Gribko argued that statements recorded secretly by a Bordentown police sergeant showed racial animus against African-Americans.
Jurors listened to the recordings between Nucera, who is white, and another officer, in which racist language was used.
And looking at the September 2016 incident, in which Nucera slammed the head of a handcuffed man into a door jamb during his arrest at a Ramada Inn, officers who testified in the case had "nothing to gain and everything to lose" in testifying against the man who promoted them.
Jurors also saw two videos Thursday morning and have asked for some transcripts from court proceedings.
Defense counsel Rocco Cipparone suggests an abundance of reasonable doubt, mostly through evidence the government failed to present during the seven-day trial. Cipparone says he agrees his client's racially volatile comments may be socially unacceptable, but they don't corroborate the accusations against him.
Neither Nucera nor the alleged victim took the stand during the trial, which lasted a week and a half, before Judge Robert Kugler.
The 34-year veteran, retired cop is facing three counts, including civil rights violations that could result in 20 years in federal prison if Nucera is convicted.
