An alleged victim of police brutality took the stand today to face questions from defense lawyers about his criminal history.

As News 12 has reported, Nassau Police Officer Vincent LoGiudice previously pleaded not guilty to felony assault charges for allegedly beating 20-year-old Kyle Howell. The incident was caught on camera during a traffic stop in Westbury back in April 2014.

Defense attorney William Petrillo hammered Howell about his marijuana use, multiple prior arrests and convictions for burglary and assault.

"The job of a police officer can be extremely dangerous," says Petrillo. "They're often confronted with situations during which they have to make literally split-second decisions. And how they perceive things matters. And what a police officer knows about a person prior to dealing with that person is extremely relevant."

Howell's civil lawsuit attorney Amy Marion says the defense can say whatever they want about her client's reputation.

"But we have the video tape to show what happened," she says.

The prosecution finished its case Thursday. Howell was the only witness called to the stand.

It not yet clear who the defense may call to testify in the case.
