I this cartoon just might have crossed the line. In a cartoon series called, "Conrad the Constitution" , the main character Conrad is a walking talking version of the United States Constitution. In this episode, Conrad embarks on an assassination mission to shoot Obama in the back of the head. It is eerily similar to the Lincoln assassination. Obama watches a community theatre production of Grease, when the constitution sneaks up and shoots Obama in the back of the head.
You can see the clip from the video here:
What do you think? is this acceptable?
