Too Important. :-) Be it good or bad. JFK. Hit-ler. They allo got attempts. Some succeeded some don't But it was all because of their INFLUENCE was. Being too public, doesn't seem like a good idea now. :-)
Murder is more personal, assassination is typically trying to make a political statement or "business in nature". The person that you are, completely affects the way people think of you in society. That's why they may just want to.... get 'rid of you'. There's many attempts of killing celebrities that you never thought people would want to. It's crazy!
Political motive or target is needed! Assassin: 1. a murderer, especially one who kills a politically prominent person for fanatical or monetary reasons. 2.( cap. ) one of an order of Muslim fanatics, active in Persia and Syria from about 1090 to 1272, whose chief object was to assassinate Crusaders. The Assassins (Arabic: Hashshashyyn, also Hashishin, Hassassin) were an order of Nizari Ismailis, particularly those of Persia and Syria that formed around 1092. Posing a strong military threat to Sunni Seljuq authority within the Persian territories, the Nizari Ismailis captured and inhabited many mountain fortresses under the leadership of Hassan-i Sabbah. The modern word "assassin" is derived from their name.The name "Assassin" is often said to derive from the Arabic Hashishin or "users of hashish", to have been originally derogatory and used by their adversaries during the Middle Ages. However Amin Malouf states: "The truth is different. According to texts that have come down to us from Alamut, Hassan-i Sabbah liked to call his disciples Asasiyun, meaning people who are faithful to the Asas, meaning 'foundation' of the faith. This is the word, misunderstood by foreign travelers, that seemed similar to 'hashish'". . The Masyaf branch of the Assassins was taken over by the Mamluk Sultan Baibars in 1273. The Mamluks however, continued to use the services of the remaining Assassins: Ibn Battuta reported in the 14th century their fixed rate of pay per murder. In exchange, the higher authorities allowed them to exist. The mention of Assassins were also preserved within European sources, such as the writings of Marco Polo, in which they are depicted as trained killers, responsible for the systematic elimination of opposing figures. Their power was broken during the Mongol invasion. A decree was handed over to the Mongol commander Kitbuqa who began to assault several Hashshashin fortresses in 1253 before Hulagu's advance in 1256.
