The court should simply have stated that the facts did not support the dying declaration elements and then it would never have created this new fluid definition of the confrontation clause that weighs the seriousness of the crime against the constitutional protections for the confrontation of witnesses.
The rule has always been that a dying declaration is one in which the declarant believes he is about to die. This case did not fit those facts.
Why should a dying declaration have protection? I do not understand the logic behind this.
