What is the St valentine's day massacre?

People think that because chief gangster Al Capone sought to

consolidate control by eliminating his rivals in the illegal trades

of bootlegging, gambling and prostitution. From 1924 to 1930, the

city of Chicago gained a widespread reputation for lawlessness and

violence. One February evening in North Chicago, seven well-dressed

men were found riddled with bullets inside the S.M.C Cartage Co.

garage. They had been lined up against a wall, with their backs to

their executioners and shot to death. These people were working for

"Bugs" Moran. During the height of prohibition and the never-ending

competition between gangster rivals Al "Scarface" Capone and George

"Bugs" Moran, bloody warfare was nothing new to the authorities of

Chicago. Nobody could think someone from some other state could be

involved. Al was never charged or proven mainly because he was not

there. There is another theory nobody was afraid to talk about at

that time. The theory holds that Enoch Lewis "Nucky" Johnson from

New Jersey was involved in the planning of the massacre.
