Under the Patriot Act, American law enforcement personnel have far more authority than they did before. This change in authority is designed to ensure that law enforcement can act quickly apprehend terrorists. After the terrorist attacks of September 11, many figures in government wanted to grant law enforcement more powers to observe unusual activity and act upon it. Many of the terms in the act could be perceived as too much to civil liberties, a major concern for some Americans.
Surveillance capabilities were greatly expanded under the act, which also increased regulation of financial transactions which are suspected to be tied to terrorist activity. It also greatly enhanced the ability of law enforcement to monitor foreign nationals in the United States, deporting them if it is deemed necessary.
