So I’ll bet this is why the police won’t release Holmes’ mug shot — he did dye his hair red, did call himself the Joker, and he probably gave the booking officer with the camera an extra big, terrible smile. Why give holmes the satisfaction? From NY Daily News:

“The man accused in the Colorado movie theater massacre was still behaving erratically on the day after his rampage at a midnight screening of “The Dark Night Rises” — the last film in the Batman trilogy. “Let’s just say he hasn’t shown any remorse,” a jail employee told the Daily News. “He thinks he’s acting in a movie.” A released inmate said Holmes’ behavior behind bars was increasingly irrational. “He was spitting at the door and spitting at the guards,” the inmate told The News. “He’s spitting at everything. Dude was acting crazy.”  [...] “All the inmates were talking about killing him,” Wayne Medley, 24, said as he left the facility. “Everyone was looking for an opportunity. It’s all they could talk about. [...] Holmes — who had dyed his hair red — was also wearing red clothing beneath the black body armor that terrified moviegoers saw when he opened fire early Friday morning, Danilov said. Jail guards “blacked out his windows with duct tape so no one could see him,” said Danilov. “He was cuffed in the back and had leg shackles. Six officers were walking him.” The deranged suspected killer, a former honors student and Ph.D. candidate, said nothing and walked slowly to his cell. Danilov said that if Holmes was released into the general jail population, “he won’t live to see Monday’s court appearance.””
