Beer in the United States
On January 16, 1919, the Eighteenth Amendment to the United States Constitution was enacted into law, creating the Prohibition era, wherein the production, sale and transportation of alcoholic beverages was made illegal. All legal American brewing came to a halt when prohibition was imposed, though the earlier temperance movement had already reduced the number of breweries significantly. Only a few breweries, mainly the largest, were able to stay in business by manufacturing near beer, malt syrup, or other non-alcohol grain products, in addition to soft drinks such as colas and root beers. Production and shipping of alcohol was largely confined to illegal operations that could deliver compact distilled beverages—smuggled rum and domestic moonshine—more efficiently and reliably than bulkier products such as beer.
Jury nullification in the United States
During the 19th and 20th centuries, especially in the 1950s and '60s civil rights movement era, some all-white juries acquitted white defendants accused of murdering blacks; however, the problem according to some scholars was: "...not in jury nullification, but in jury selection. The jury was not representative of the community..." During Prohibition, juries often nullified alcohol control laws, possibly as often as 60% of the time because of disagreements with the justice of the law. This resistance is considered to have contributed to the adoption of the Twenty-first Amendment repealing the Eighteenth Amendment which established Prohibition.
