And what if the USA PATRIOT Act did not exist? How would police investigative and other activities be influenced?

Explanation:

The USA PATRIOT Act also known as the Patriot Act was signed by former U.S president George Bush. It is an acronym which stands for Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001. The Act was to punish and deter terrorist acts in the country and to enhance law enforcement investigatory tools.

Since after the terrorist attack in 9/11, United States has increased its surveillance of terrorist activity. It has given the right for people to be prosecuted even though information was gathered without a proper criminal search warrant.
