As I will explain, I have concluded that the factors to be considered on the admissibility inquiry cannot be categorized in terms of threshold and ultimate reliability. Comments to the contrary in previous decisions of this Court should no longer be followed. Rather, all relevant factors should be considered including, in appropriate cases, the presence of supporting or contradictory evidence. In each case, the scope of the inquiry must be tailored to the particular dangers presented by the evidence and limited to determining the evidentiary question of admissibility.
