events, if at all. Access to famous people also became more and more restricted; potential visitors would be forced through numerous different checks before being granted access to the official in question, and as communication became better and information technology more prevalent, it has become all but impossible for a would-be killer to get close enough to the personage at work or in private life to effect an attempt on their life, especially with the common use of metal and bomb detectors. Most modern assassinations have been committed either during a public performance or during transport, both because of weaker security and security lapses, such as with U.S. President John F. Kennedy and former Pakistani Prime Minister Benazir Bhutto, or as part of a coup d'état in which security is either overwhelmed or completely removed, such as with Congolese Prime Minister Patrice Lumumba. The methods used for protection by famous people have sometimes evoked negative reactions by the public, with some resenting the separation from their officials or major figures. One example might be traveling in a car protected by a bubble of clear bulletproof glass, such as the MRAP-like Popemobile of Pope John Paul II, built following an attempt at his life. Politicians often resent the need for separation and sometimes send their bodyguards away from them for personal or publicity reasons. US President William McKinley did so at the public reception in which he was assassinated. Other potential targets go into seclusion and are rarely heard from or seen in public, such as writer Salman Rushdie. A related form of protection is the use of body doubles, people with similar builds to those they are expected to impersonate. These people are then made up and, in some cases, undergo plastic surgery to look like the target, with the body double then taking the place of the person in high-risk situations. According to Joe R. Reeder, Under Secretary of the Army from 1993 to 1997, Fidel Castro used body doubles. US Secret Service protective agents receive training in the psychology of assassins.
