Visible Extra Security Measures and Prison Garb. The Due Process Clause prevents the government from taking certain security measures during trial that are prejudicial to the defendant in the absence of some essential government interest. During both the guilt and penalty phases of trial, the government may not use visible shackles on the defendant unless there is a special need, such as special security concerns or escape risks. However, placing uniformed security officers in the courtroom generally does not violate the defendant's due process rights.

The defendant also cannot be compelled to stand trial before a jury while dressed in identifiable prison clothing. However, if the defendant fails to object to wearing prison clothing, the compulsion necessary to establish a constitutional violation is negated.
