Can a court impute to the arresting officer the collective knowledge of law enforcement agencies for the purpose of establishing probable cause?

There is language in the cases which indicates that a court may impute to the arresting officer the collective knowledge of law enforcement agencies for the purpose of establishing probable cause. (See, e.g., People v. Ramirez (1983) 34 Cal.3d 541, 547, 194 Cal.Rptr. 454, 668 P.2d 761.) However, with the limited exception noted below, in each case we have found, there has been the requirement that there must exist in one place [150 Cal.App.3d 699] sufficient information to constitute probable cause. That place then initiates the directive relied upon by the officer in the field who makes the stop.
