To carol1415 - You claim that Obama (and Hilary) "KILLED 4 Americans in Libya". Now, I wasn't there of course, but I'm fairly certain that they did no such thing.
And if you think this incident amounts to the "the biggest COVER-UP of all times [sic]", then I'd wager you aren't too familiar with American history.
Does it only matter to you when Americans die? What about the thousands of innocent people we've slaughtered? Is the life of an innocent Yemeni civilian intrinsically of less value than, say, your own?
And please, the "all-capping" doesn't add anything to your (non) arguments.
