Both sources J and I are about the scheme that prohibition caused with Americans throughout the 1920s and early 1930s. Source I is a cartoon from the period of prohibition.

A policeman wrote source J, it is about Chicago, the centre of gangsters in America, in the 1920s. The source is about corruption and bribery. He talks about how even the police force is giving in to corruption, he says, "it was a conspiracy and my senior officers were involved in it." He says that he could not enforce the law at all because corruption was too great and he would end up being punished for it. Policemen had to go along with the bribery and crime because otherwise they would be left alone with an awful job.

So to conclude, Source I does support source J to a certain extent. The two sources are about how corruption became so large during the times of prohibition. Source J explains how gangsters are bribing high ranking officials; this is supported by the politicians, prohibition officers and magistrates, ready to take bribes in source I. Source I also proves the point that the gangsters are taking over Chicago, which is implied in source J. Source I proves this because it shows all the people ready to take bribes, therefore the gangsters are in complete control of these people. Source J explains how and why prohibition is failing; this is backed up by the image of the people that are meant to be enforcing prohibition ready to take bribes. However, source I does not prove every point made in source J. Source I shows a great variety of people ready to take bribes whereas source J mainly concentrates on the corruption within the police force. So overall, source I does prove a lot of what source J states.
