WASHINGTON ( CNN ) -- The man charged with murder in the shooting death of a guard at the U.S . Holocaust Memorial Museum was denied bail Wednesday and will undergo psychiatric testing against his will . `` Your Constitution guarantees me a speedy and fair trial , '' James von Brunn said from his wheelchair . James von Brunn ignored the advice of the judge and his defense attorney and addressed the court during a hearing to fight any delays as prosecutors press their case . `` Your Constitution guarantees me a speedy and fair trial , '' he said from his wheelchair during the hearing before U.S. District Judge Reginald Walton . But Walton granted the defense request for a mental evaluation , which will take place within the next 30 days at a facility in Butner , North Carolina . Von Brunn , a self-avowed white supremacist , will remain in custody after the judge said there were no conditions for release that would protect the public . Federal prosecutor Nicole Waid said von Brunn is `` dangerous because this defendant has nothing to lose , '' and that he wants to be `` a martyr for his cause . '' Von Brunn 's attorney , public defender A.J . Kramer , did not challenge the government 's request to deny bail , saying `` we do n't have any evidence to offer at this time . '' Kramer also convinced the judge to order a competency exam , which will include observations as to whether von Brunn understands the charges and can assist in his own defense . Prosecutors said four of the charges in the indictment are capital offenses and could mean the death penalty if he is convicted . Waid told the judge the government 's evidence is `` overwhelming '' and includes security camera video from the June 10 attack , in which von Brunn is seen raising a gun and shooting guard Stephen Tyrone Johns , who had opened the door for him . As Johns stumbled back mortally wounded , Waid said , `` you can see the defendant fire two more times , '' before he is shot and wounded by other guards . Also seen on the tape is the weapon being taken from von Brunn 's hands , the prosecutor said . During the discussions about psychiatric testing , von Brunn looked at spectators in the courtroom and shook his head as if to say `` no , '' when it became clear he would not be arraigned on the charges unless he is deemed competent . `` Mr. von Brunn , I advise that you not speak , '' the judge said , explaining that his attorney can best represent him . But von Brunn ignored his advice . `` I 'm a United States citizen , and as a U.S . Naval officer , I swore to protect my country , '' he said . `` I take my vows very seriously . '' The 89-year-old World War II veteran did not explain his remarks .
