Answer:
The USA Patriot Act is a federal law passed in the United States in October 2001 that gives the government and the police wide powers to supervise citizens, adopted after the terrorist attack of September 11, 2001. The law, in particular, expanded the FBI's rights of eavesdropping and electronic surveillance, which was seen by many as a violation of the fourth constitutional amendment.
The Patriot Act was criticized for interfering with privacy and allowed the CIA to more easily intercept phone calls, infiltrate groups and, without applying for permission, find out what books individuals have borrowed, people's education, illnesses and hospital stays.
