Answer:
Given the pervasive lawlessness during Prohibition, bootlegging was omnipresent. The operations varied in size, from an intricate network of bootlegging middlemen and local suppliers, right up to America's bootlegging king, George Remus, who operated from Cincinnati, lived a lavish lifestyle, and amassed a $5 million fortune. To escape prosecution, men like Remus used bribery, heavily armed guards, and medicinal licenses to circumvent the law. More ruthless gangsters, such as Capone, did not stop at crime, intimidation, and murder.
Under those conditions, the nation's cities were ripe for crime. In cities like Pittsburgh and Cleveland, numerous ethnic gangs fought to control the local bootlegging activities. In Chicago, 800 gangsters were killed in gang warfare during Prohibition, primarily due to the fight over alcohol sales.
Bootleggers counterfeited prescriptions and liquor licenses to gain access to alcohol. The most common practice was to import liquor from other countries aboard ships. The river between Detroit and Canada was a thriving entry point, as was the overland method on the long border between the two countries. Bootleggers also evaded authorities by building secret breweries with intricate security systems and lookouts. In addition to eluding the police, bootleggers had to fend off other bootleggers who would steal the precious cargo for their own sale. Bootleggers began a national controversy by selling adulterated liquor, which resulted in countless fatalities and poisonings.
