The Assassination of Reverend Martin Luther KingContributed by Alex Shrugged
- "There’s no way in the world you can keep somebody from killing you if they really want to kill you."
- -- Martin Luther King, 1968, when asked why he has no bodyguard. 
This Year in SpaceContributed by Southpaw Ben
1968 was a major year is space flight, with some of the most historic space missions taking place. No, not THAT one, that isn't until next year. We do, however have the December 21st Apollo 8 mission, which was the first manned spacecraft to leave Earth's orbit, and reach the Moon. Originally this mission was planned to take place with Apollo 9, and Apollo 8 was to test the lunar module in low Earth orbit. This all changed, however, with the successful launch and recovery of the Zond 5 spacecraft, which was the second ship to circle to the moon. (The first was the Zond 4, which self-destructed during re-entry as it went off course as wasn't going to land in USSR controlled territory.) However, Zond 5 was especially notable, because it successfully was recovered, and because it contained plants and animals, which were only slightly affected by the trip, most notably the two tortoises who lost about 10% of their body weight, but were otherwise in perfect condition.    
More Control Over Guns. Yeah. That Will Fix it!Contributed by Alex Shrugged
Senator Robert Kennedy is assassinated by a wild-eyed Palestinian. Former defensive tackle, Rosey Grier, wrestles the shooter to the ground. Dr. Martin Luther King is assassinated. There are riots in the streets! Something must be done! So... Congress does something. The first gun control laws were meant to keep firearms out of the hands of ex-slaves, but even in modern times black people have been denied access to self-defense. In fact, Reverend King was denied a firearms license because a threat to one's life is not sufficient cause. A few decades ago, the federal government limited possession of machine guns, and set a legal age for purchasing firearms. A new gun control bill has been languishing in Congress since the assassination of President Kennedy, but with the death of Robert Kennedy, and Reverend King, it gets pushed through. The new law bans mail order sales of rifles and shotguns because Oswald had bought his rife through the NRA magazine American Rifleman. They also prohibit the mentally ill from purchasing a weapon. (Does that include Congress?) The long list of prohibited persons includes: felons, drug users, illegal aliens, dishonorably discharged veterans, people convicted of misdemeanor domestic assault (essentially wife-beating) and more.
