explain what al capone did tho
I found an article that stated the following:
It was reported that one of Capone's family members in Chicago became ill from drinking expired milk. At that time, there were no controls on milk production, neither expiration dates nor controls on adulteration, dilution or skimming of the cream.
This drew Capone's interest to the milk business, and he saw several things: the milk distribution business had a shady character – and Capone was comfortable with shady businesses; he didn't like to see people, especially children sickened by adulterated milk; he saw a potentially high profit in milk distribution; and with Prohibition soon to end, he had a fleet of trucks that could easily be used to transport milk.
Capone took two steps to move into the milk business. One was to acquire a milk processor, Meadowmoor Dairies. The other was to have the Chicago City Council pass a law requiring a visible date stamped on milk containers.
On the second item, it was likely that Capone had already cornered the market on equipment to stamp expiration dates on bottles, and the passage of the legislation would help him take over the Chicago milk market.
In 1930s Chicago, before refrigeration and supermarkets, milk was delivered by the milkman, a teamster's union member. The union controlled the distribution of milk, whose freshness depended on how long the milk sat around until the driver delivered it.
The unions would only deliver local milk. Meadowmoor Dairies wanted to import cheeper milk from Wisconsin, and wanted it delivered by their own nonunion truckers.
With the negotiations at a standstill, Capone's people reportedly kidnapped the union president and used the $50,000 ransom to purchase the dairy. The dairy was given as a present to Capone's attorney, William Parrillo. Meadowmoor Dairies opened three months before Capone went to prison.
