A mock execution is a stratagem in which a victim is deliberately but falsely made to feel that their execution or that of another person is imminent or is taking place.
 It may be staged for an audience or a subject who is made to believe that they are being led to their own execution.
 This might involve blindfolding the subjects, making them recount last wishes, making them dig their own grave, holding an unloaded gun to their head and pulling the trigger, shooting near (but not at) the victim, or firing blanks.
 Mock execution is categorized as psychological torture.
 There is a sense of fear induced when a person is made to feel that they are about to be executed or witness someone being executed.
 Mock execution is considered psychological torture because there is no physical harm caused, but there is mental harm.
 Psychological harm is caused because the victim's suspense level increases while awaiting their death or someone else's, which is considered torture.
 The psychological trauma begins to occur when the victim starts to believe that they are about to be executed.
 The buildup of anxiety due to mock execution could influence the end result of the staged death.
