Jerica Knox wrote a paper arguing that airport security in the United States has not improved enough since 9/11 and that further improvements are needed. While some security measures have been implemented, such as increased screening procedures and the creation of the Transportation Security Administration, terrorists continue to find ways to bypass security. The Department of Homeland Security also needs restructuring to better organize security efforts and share information. The paper concludes that both government agencies and citizens must work together to continuously strengthen airport security measures in order to safeguard innocent lives.
