So Aurora shooter James Holmes has “lawyered up” and “is not cooperating” – you’d think he did something wrong

If law enforcement spokespeople are to be believed, James Holmes has “lawyered up”, EXCEPT that he turned up at his arraignment alone, with a public defender. Does “lawyered up” mean something else, like invoking your right not to be interrogated without advice of a lawyer? Was the statement meant to fill in the villainous mold according to the public’s “law and Order” TV notion about how police can mistreat suspects? By surrendering himself, by warning officers about his boobytrapped apartment and now telling of the notebook he’d mailed to his university, James Holmes’ behavior seems to contradict everything the police are pretending. There’s nothing to defend about the Aurora shootings, I mean that outside the courtroom, but why add stripping ourselves of our right to remain silent as we cheer for James Holmes’ blood?
