The US military has done an excellent job of censoring images like these. Perhaps if they hadn't been so skilled at denying free speech, support for the war in Iraq would have declined sooner rather than later.

By the way, you are allowed to react to these images with your emotions. That's what makes you fully human. Don't let anyone tell you that you should view them solely from the cold aspect of reason. Such people are only censors of a different sort. They would censor your feelings.
