The second of two state-appointed psychiatrists who examined the Colorado theater gunman is testifying at James Holmes' trial in suburban Denver.

Excerpts of William Reid's 22 hours of videotaped interviews with Holmes were played on the trial's opening day. In one, Holmes called people wounded in the attack "collateral damage."

District Attorney George Brauchler told jurors at the time that Reid concluded Holmes was legally sane.

But before Reid took the stand Thursday, Judge Carlos Samour said Reid won't be able to say whether Holmes had a particular mental state at the time of the July 2012 mass shooting.

Holmes has pleaded not guilty by reason of insanity in the attack at an Aurora movie theater that killed 12 people and injured 70.

Under Colorado law, the burden of proof is on prosecutors to convince jurors that Holmes was sane and knew right from wrong.
