How has the us government used the patriot act to prevent terrorist attacks since september 11, 2001?
by using electronic surveillance of suspected terrorists
by offering rewards to terrorists who turn themselves in
by keeping information about suspected terrorists private
by opening its borders to better track suspected terrorists

The Patriot Act allows police to install Internet pen registers without demonstrating probable cause that the suspect is engaged in a criminal activity. By revealing the URLs of Web sites visited by a suspect, a pen register is a much more powerful surveillance tool on the Internet than it is on a telephone network.
