Final answer:
Giles Corey did not become an expert in legal matters. The question seems to be confusing two different historical figures - Giles Corey and Clarence Gideon.
Step-by-step explanation:
Giles Corey did not become an expert in legal matters. The question seems to be confusing two different historical figures - Giles Corey and Clarence Gideon. Giles Corey was a farmer from the late 17th century who was accused of witchcraft during the Salem witch trials in Massachusetts. He was not an expert in legal matters, but his refusal to enter a plea and endure torture in order to protect his land and property became a notable example of civil defiance.
On the other hand, Clarence Gideon was the defendant in the landmark Supreme Court case of Gideon v. Wainwright in 1963. Gideon was convicted of a felony in Florida and was denied legal representation because he could not afford a lawyer. He took up his own defense during his trial and was ultimately found guilty. However, while in prison, he filed a handwritten appeal to the Supreme Court arguing that he had been denied his constitutional right to legal representation. The Supreme Court ruled in Gideon's favor, establishing the right to legal counsel for all defendants, regardless of their ability to pay. This case played a significant role in shaping the criminal court system in the United States.
