Security theater is the practice of implementing security measures that are considered to provide the feeling of improved security while doing little or nothing to achieve it.[1][2]
The term was originally coined by Bruce Schneier for his book Beyond Fear[3] and has since been widely adopted by the media and the public, particularly in discussions surrounding the Transportation Security Administration.[4]
The use of Security theater tactics is a somewhat controversial subject that involves discussions of alleged discrimination, and potential economic disadvantages. Therefore, the term has a negative connotation and is used as a means of critiquing.[3]
Practices called into question by the critiques of security theater include airport security measures, stop and frisk policies on public transportation, and clear bag policies at sports venues.[5][6][7]
