Washington Wizards three-time All-Star guard Gilbert Arenas should get three months in jail for bringing guns into the team's lockerroom, prosecutors said on Tuesday, but defense lawyers urged probation and community service.

The two sides filed court documents before Friday's scheduled sentencing for Arenas, who pleaded guilty on Jan. 15 to felony weapons possession for bringing four guns into the National Basketball Association team's lockerroom.

Under a plea deal, prosecutors agreed not to seek more than six months in a local jail for Arenas. But Superior Court Judge Robert Morin is not bound by the agreement and could sentence Arenas to as little as probation or as much as five years in prison.

Assistant US Attorney Christopher Kavanaugh said in a 26-page sentencing memo that Arenas, 28, should get three months' incarceration, three years of probation and be required to do 300 hours of community service.

He said evidence uncovered by the government contradicted claims by Arenas on when and why he brought the guns to the locker room, that Arenas feigned ignorance of the law to lessen the significance of his acts and that he attempted to minimize the extent of his guilt.

Arenas "has shown little genuine remorse for anything other than how this incident may affect his career", Kavanaugh said. "Contrary to the defendant's claim, his conduct was not a laughing matter."

Defense attorneys replied in a 37-page memo that Arenas had accepted responsibility and that justice would be best served with a sentence of probation and community service.

"Mr. Arenas is a man with an abundance of admirable character traits," Kenneth Wainstein wrote.

"He is a genuinely caring person, he has long devoted himself to serving the community and others and, despite a history of pranks and misguided practical jokes, he is a peaceful man who is not aggressive or confrontational in any way," Wainstein said.

He said countless individuals had come forward to tell personal stories about Arenas, ranging from brief encounters when Arenas was generous with his time to long-term friendships.

"This input ... paints a picture of a man who is somewhat off-beat but fundamentally very decent and unfailingly kind to others," Wainstein said.

At the end of January, the NBA suspended Arenas and teammate Javaris Crittenton without pay for the rest of the season for bringing guns into the lockerroom.

The two players brought the guns to the team's arena after a dispute during a flight home from a game in December. Crittenton has also pleaded guilty and was sentenced to one year of probation.
