`` Patriot Act '' allows law enforcement officers to search a home with permission or consent of the owner .
Opponents of the law have criticized its authorization of indefinite detentions of immigrants ; the permission is given law enforcement officers to search a home or business with the owner 's or the occupant 's consent and knowledge ; the expanded use of `` National Security Letters '' , which allows the `` Federal Bureau of Investigation '' , `` FBI '' , to search telephone , e-mail , and financial records without a court order ; and the expanded access of law enforcement agencies to business records , including library and financial records .
