Growing up (I'm now 49), we were often told ignorance of the law is not an excuse. What this meant was that is was our responsibility to know the law. However, the Obama Administration has used this excuse every time something bad has come up. During Fast and Furious, we heard Holder cry that he didn't read his emails. Jon Corzine used that excuse regarding the debacle at MF Global. Now, we get the same excuse regarding Libya. The media will never press them, so they continue to peddle the same thing time and time again.
