Jason Brevoort Brown was an opportunist, a lawyer and politician in Indiana during the last half of the 19th century. He represented the Jackson County, IN area in the state legislature off and on from the early 1860s thru the 1880s. He was in Congresss for three terms in the 1890s. And he was appointed Secretary of Wyoming Territory in 1873.
But through most of those years—often behind the scenes—he was the lawyer for the Reno Gang of Indiana, defending them (usually successfully) against a variety of charges, from train robbery to murder to counterfeiting.
