The American Revolution

Question:
The American Revolution arose partly in response to British general search warrants, which gave arbitrary and intrusive powers to government officers. Thus, the founders created the Fourth Amendment to protect against unreasonable and warrant-less intrusions of privacy by a powerful and partisan federal government. During the 20th century, countless dictators have used arbitrary and intrusive surveillance to monitor and suppress dissidents. Any democracy that does not enforce equally extensive protections will systematically suppress dissent.

Which of the following, if true, best weakens the argument?

a) The United Kingdom’s parliamentary system does not have such extensive protections but has never systematically suppressed dissent.
b) Many dictators have been very beneficial and constructive leaders for their countries.
c) Many democracies have haphazardly used surveillance to monitor dissidents and suppress dissent during times of war.
d) Some dictators have been supported by the United States.
e) At least some countries in the former Soviet Union now have democratic elections but still suppress dissent.
