Barack Obama, the 44th president of the United States, was involved in multiple security incidents, including several assassination threats and plots, starting from when he became a presidential candidate in 2007. Secret Service protection for Obama began after he received a death threat in 2007, while serving as the junior United States senator from Illinois and running for president. This marked the earliest time a candidate received such protection before being nominated.[1] Security was increased early for Obama due to fears of possible assassination attempts by white supremacist or other racist groups or individuals against the first African American major party presidential nominee.[2][3][4]

Elmer J. McCurdy (January 1, 1880 – October 7, 1911) was an American outlaw who was killed in a shoot-out with police after robbing a train in Oklahoma in October 1911. Dubbed "The Bandit Who Wouldn't Give Up", his mummified body was first put on display at an Oklahoma funeral home and then became a fixture on the traveling carnival and sideshow circuit during the 1920s through the 1960s. After changing ownership several times, McCurdy's remains eventually wound up at The Pike amusement zone in Long Beach, California, where they were discovered by crew members for the television series The Six Million Dollar Man and positively identified in December 1976.
