Lawyers for Aurora theater-shooting suspect James Holmes are challenging the constitutionality of Colorado's laws for insanity pleas, introducing a complicated new argument into his case.
In a flurry of motions filed Thursday and made public Friday, Holmes' attorneys question whether the requirements for an insanity plea violate defendants' rights against self-incrimination. They also argue that the laws provide less protection for people facing the death penalty—as Holmes might—than for defendants facing prison terms.
