If a police officer has reason to suspect that an unrelated crime was or is about to be committed, is this a pretextual stop?

If the police have a reasonable suspicion that an unrelated crime was or is about to be committed an automobile stop is justified on that ground alone. People v. Tillie, 239 A.D.2d 670, 657 N.Y.S.2d 791, 794 (3d Dep't 1997). If "reason to suspect" is not equivalent to "reasonable suspicion," so long as the officers intend to stop an automobile for a traffic offense, whatever other motivations they simultaneously entertain appear to be irrelevant under Washington. Thus the conclusion that a stop is not pretextual if "based upon the officer's observation" of a violation of the vehicle and traffic law, People v. Jackson, 241 A.D.2d 557, 661 N.Y.S.2d 247, 248 (2d Dep't 1997), is simply the outcome of an objective test.
