After the war, Badger settled in New Orleans, where he was appointed as a clerk in Fourth District Recorders Court. About 1868, he joined the Metropolitan Police and was promoted in 1869 to superintendent. On September 14, 1874, Badger was seriously wounded in the Battle of Liberty Place, an insurrection by 5,000 members of the paramilitaryWhite League, who fought against the police and took over state buildings in an attempt to seat John McEnery, the Democratic candidate for governor in the disputed 1872 election. The White League outnumbered and outgunned the Metropolitans, holding the buildings for three days, and retreating before the arrival of federal forces. Nearly sixty people were killed in the fighting. No charges were filed against any insurgents. Badger left the police force in 1875 to serve as state tax collector in New Orleans. In 1878, during the administration of Republican President Rutherford B. Hayes of Ohio, Badger was named postmaster at New Orleans. After a year, he took another patronage position, as special deputy in the New Orleans Customs House, at which he worked until 1885. That year, the Democratic administration of President Grover Cleveland of New York replaced him with their own appointee. In 1880 he served as part of the Louisiana delegation to that year's Republican National Convention held in Chicago. In 1889, with the return of a Republican administration under President Benjamin Harrison of Indiana, Badger was appointed as special deputy of the US Customs Service. In 1890 he was appointed as the US Appraiser of merchandise in the Customs Service at New Orleans; his post ended in 1893 with a change in administrations. Badger returned to the appraiser position about 1900, under the Republican William McKinley administration, and held that final position until his death in 1905 at the age of sixty-five.
Family and civic life
On April 30, 1872, Badger married Elizabeth Florence Parmele, daughter of Frederick F. and Jane Parmele. The couple had four children, Sidney, Frederick Parmele, John Algernon, and Harry Sprague. Elizabeth died in 1880. On September 9, 1882, Badger married Blanche B. Blineau, the daughter of John Blineau and the former Amelia Dechamps, who were both of French descent. They had two children together: George Chester Badger and Marion. Badger on more than one occasion led the New Orleans Mardi Gras procession of the Krewe of Rex in his capacity as police superintendent. In one appearance, some in the crowd lampooned him as a "sleuthing bloodhound with a large protruding nose." Like many men of his time, Badger joined the many fraternal organizations: he was a member and officer of the Grand Army of the Republic veterans organization. He was a grand commander of Knights Templar and a member of the Masonic lodge. He was Episcopalian. Badger died in New Orleans and is interred there at Metairie Cemetery.
