concurring separately: I concur in the result and wish only to express this one time my reservation about the approach to *767State constitutional adjudication adopted in State v. Ball, 124 N.H. 226, 471 A.2d 347 (1983), and followed here. When a federal constitutional standard is binding upon us and we do not question the soundness of the result it would require, I would rest the decision of the case on the federal standard. I would concentrate on the development of State constitutional law in those cases when a State rule would be different from its federal counterpart and would affect the outcome. I believe that over the long term, the adjudicatory process is likely to lead to sounder results when a practical difference is at stake.
