The 1889 death of inmate Taylor Combs led to a scandal, and then major reforms, at the Rochester State Hospital for the Insane.

The O'Connor layover agreement was instituted by John O'Connor shortly after his promotion from St. Paul detective to chief of police on June 11, 1900. It allowed criminals to stay in the city under three conditions: that they checked in with police upon their arrival; agreed to pay bribes to city officials; and committed no major crimes in the city of St. Paul. This arrangement lasted for almost forty years, ending when rampant corruption forced crusading local citizens and the federal government to step in.

The Minnesota Commission of Public Safety (MCPS) was a watchdog group created in 1917. Its purpose was to mobilize the state's resources during World War I. During a two-year reign its members enacted policies intended to protect the state from foreign threats. They also used broad political power and a sweeping definition of disloyalty to thwart those who disagreed with them.

Ann Bilansky was the only woman executed by the action of Minnesota courts. She died in 1860, but doubts about her guilt remain alive.

In the early morning of June 2, 1895, Houston Osborne, a young African American man, broke into Frieda Kachel's bedroom in her St. Paul home. When Kachel screamed, Osborne ran; he was caught and hanged from a cottonwood tree but let down while he was still alive. He died in prison eighteen months later.

Minnesota's first experiment in juvenile justice, the State Reform School, operated in St. Paul from 1868 to 1891. During that time, over 1250 inmates, almost all of them boys, were committed to the institution, mostly for petty crimes and "incorrigibility." The school moved to a new facility in Red Wing in 1891.

In 1854 legislators in St. Paul requested a grant from the federal government to create a rail line across Minnesota Territory. Public outcry led to scandal and the repeal of the territory's first land grant bill.

On August 21, 1860, enslaved African American Eliza Winston was freed from her Mississippi slaveholder in a Minneapolis court. After being granted legal freedom, however, Winston faced white mob violence and was forced to leave the area. The event showed that although slavery was illegal in Minnesota, many white Minnesotans supported the practice when it economically benefited them.

Early generations of Minnesotans lived with the ever-present danger of fire. Many city histories tell of blazes that destroyed whole sections of their communities, but in most cases arson was not the cause. The Red Wing Mills complex, however, was almost certainly burned deliberately by an unknown arsonist.

Speaking out against U.S. involvement in World War I had its hazards for Minnesota citizens. In Goodhue County such talk resulted in imprisonment.
