What kind of impact did Al Capone have on society?

His kind of impact is that he showed that laws cannot be made that go against the will of the people.

It started with the Halstead act which banned alcohol but people wanted alcohol. So Capone and the others stepped in to do something about it.

They didn't see the illegality that they were breaking the law yet the people wanted these products and did find no harm in alcohol. So after making alcohol illegal again did the gang disappear.
