The Saint Valentine's Day Massacre was a major organized crime event in Chicago. It occurred on February 14, 1929. Seven men were killed during the attack at a garage in the Lincoln Park neighborhood. This event happened during the Prohibition era in the United States. Prohibition was a period when the manufacture and sale of alcohol were illegal. 
The attack was carried out with a specific, deceptive method. Between four and six men arrived at the garage in a black Cadillac. Two of these men wore police uniforms to trick onlookers. They entered the garage and forced seven men to line up against a wall. The gunmen used Thompson submachine guns and a sawed-off shotgun to shoot the victims. They fired seventy rounds from the machine guns. One cartridge was also fired from the shotgun. The gunmen then left the scene. They acted like police officers making an arrest to avoid suspicion.
There were two main criminal organizations fighting for control in Chicago. The North Side Gang was led by George "Bugs" Moran. Moran earned his nickname from his intense stare and temper. The other group was the Chicago Outfit. This organization was led by Al Capone. 
Historians and police have long debated the cause of the massacre. Many believe the attack was an attempt to kill George "Bugs" Moran. However, Moran was not at the garage when the shooting began. He drove past the area and avoided the attack by getting coffee. The victims in the garage included Moran's second-in-command, Albert Kachellek. They also included Adam Heyer, a bookkeeper, and several enforcers. Other men present were not gang members, such as a mechanic named John May. The massacre was a targeted strike that missed its primary goal.
Investigations into the crime used new scientific methods. Calvin Goddard, a pioneer in forensic ballistics, set up a lab in Chicago. His team studied evidence like bullet fragments to find clues. 
The violence of the massacre had a major impact on American law. The use of Thompson submachine guns in such public crimes worried the nation. This specific type of violence led to the National Firearms Act of 1934. This law was created to regulate certain types of weapons. The massacre also showed the scale of organized crime. During Prohibition, the homicide rate in Chicago rose by 21 percent. The Chicago Crime Commission identified 729 gang-related murders in Cook County between 1919 and 1933. This represented 15 percent of all murders in that area.
Today, the Saint Valentine's Day Massacre remains a significant historical topic. It is frequently discussed in history books and academic studies. The event has also been depicted in many films and television shows. It serves as a clear example of the era of Prohibition. It shows how illegal markets can drive intense competition and violence. The event changed how the public viewed the power of criminal organizations. It also changed how the government responded to gun violence in the United States.
