Will President Obama Be Killed Like Pres. John F. Kennedy?

Who is truly guarding the life of President Barack Hussein Obama?  There have been many breaches in security concerning the life of our president and the first family.  All of these incidents are connected to an unconcerned or unequipped secret service organization.  Will the tank-like barracated Limousine be a safehaven for our president or will this be the coffin to transport his body?  Shall the coolness of his posture be enough to shepherd his flock? Or shall his death ignite an unquenchable flame to set the black race on a revolutionary path of violence and bloodshed?
