What is the test for issuing a warrant for the search of a car by a police community support officer?

The central question in a review of whether a warrant has been issued on probable cause is whether the issuing official had a " 'substantial basis for ... conclud[ing]' that a search would uncover evidence of wrongdoing." Illinois v. Gates, --- U.S. ----, 103 S.Ct. 2317, 2331, 76 L.Ed.2d 527 (1983) (quoting Jones v. United States, 362 U.S. 257, 271, 80 S.Ct. 725, 736, 4 L.Ed.2d 697 (1960)). There is no question here that probable cause existed to issue a warrant for the search of the car. In my view, however, there was lacking a substantial basis for concluding that evidence relating to the robbery would be uncovered in a search of the house.
