Lattimer wanted a witness to testify in Spanish. Mapp thought the man spoke “excellent’’ English, and denied Lattimer’s request.

According to a news report, Lattimer said he couldn’t obey the instruction, and that the judge would have to find him in contempt. Mapp promptly did so, then had the young lawyer hauled out in handcuffs.

Lattimer spent 30 minutes of a 30-day sentence behind bars, and later told a reporter: “It was horrible.’’

Mapp was no less tough on defendants. In 1979, he sentenced a 46-year-old roofer to a year in jail for driving without a license and making an improper turn.

A newspaper story noted that such infractions usually brought a two-month sentence, but Mapp, who called the defendant “a menace to society,’’ took into account the driver’s many drunk-driving arrests.

Mapp, who graduated from Atlanta’s Morris Brown College, joined the segregated Miami Police Department in 1952.

When he left in 1960, the department still hadn’t integrated. Mapp had spent his police career in the lone all-black precinct, where they were called “patrolmen’’ rather than officers, and were forbidden to arrest whites.

He also taught in traffic school.

While in the department, Mapp sponsored a group for black teens who sought to curb “adult delinquency.’’ He told the Herald in 1954 that he was especially concerned about unreported child molestation.

“These teenagers can do a lot of good,’’ he said. “They get around a lot and they know what’s going on.’’

When he left the department, Mapp enrolled at Howard University Law School, worked summers as a waiter at the Canadian Embassy in Washington, and “came home when he could,’’ his son said.

State Attorney Richard Gerstein hired Mapp in 1963. He left for private practice with the newly-formed firm of Mathews and Mathews, Braynon, and Mapp.

But, said his son, he never lost his affinity for physical work. When he came home from the courthouse, Mapp would “get on his riding lawnmower and get out his weed eater. Dad just wanted to do whatever was opposite of his work life.’’

In addition to his son Corey, Mapp is survived by son Calvin R. Mapp Jr.
