There are a few problems with your "logic." First, the only people upset about this are folks that wouldn't vote for him anyway, regardless of what kind of job he was doing. The folks who it ain't gonna set well with weren't gonna vote for him. It will appeal to many more than it will disgust. Plus, you saying Barack has no clue. I'd counter with Republicans have no clue, but this issue is really making them look stupid among independents (the group that really swung the 2008 election), especially the 18-49 group that can most identify with rap music. Second, the song is about Assata Shakur, a woman who's story is very popular in the hip-hop community among the more "conscious" poets. Noone ever denied that Assata likely did some horrible things, but modern day examinations of the logistics of the Turnpike trial reveal that she was unlikely to have been anything more than just there at the wrong time. She had been on trial for countless other crimes, despite overwhelming evidence of her lack of involvement. She was never convicted of any of those crimes. Medical evidence revealed it would have been impossible for her to fire a gun because of where she was shot. It further revealed that the only way she could have been shot in the places she was shot was if she was raising her arms to surrender, basically meaning she was innocent and didn't shoot, nor serve as an accomplice to the shooting of, anyone. There is no doubt she affiliated with unsavory groups. There is also no doubt that she was a target of the FBI's COINTELPRO operation that targeted any "radical" black person courageous enough to speak out against wrong-doing against black people. Malcolm X and MLK were likewise COINTELPRO (or earlier iterations of the same program) targets. So basically, many in the hip-hop community, while acknowledging she is more than likely a criminal, feel she's innocent of THIS crime. But if it were not for this crime, she would not be convicted of anything. Third, for all the attention on that one song, Common has COUNTLESS other songs decrying violence of any sort against anyone. His lyrical expression abilities and use of metaphors to tell a story are considered among the best ever in the hip-hop community. The admitted problem with my rebuttal is simple. Folks who have a problem with Common being at the White House by and large will not bother to do any research on the song or on the song's subject to see from where the song is rooted. The headline stating that Common wrote a song supporting a cop-killer will be enough for them. Not to mention he plays a gun-toting criminal in nearly all of his acting roles won't help. But he loves those roles because they're so far from his true personality. Sorry for the long reply, and I wouldn't be surprised if you didn't bother to read it, but simply saying "It's not what you think" wouldn't suffice. I also don't expect it to change your mind at all. Just telling the other side of the story.
