That such police subterfuge can't be used for bulk dragnets where "we'd all be searched" is irrelevant: there, it'd be obvious (when the followup search usually fails) that some fishy overreach is happening. In this particular surveillance-tipped condition, you are asserting there's still some useful check from the necessity of "articulable probable cause". But because of the strong (and legally out-of-band) tip, very few searches are necessary, the searches always succeed in finding contraband, and the only contrary witness to the flimsy smell/dog/eyes/joint-on-the-seat probable-cause rationale is the suspect himself -- whose credibility is shot by the successful find. That's what makes the phony 'probable cause' tricks trivial in these cases, and your reassurances hollow. And once the authorities have started down the road of deception of the courts to get a conviction, it's only a small additional step to planting the drugs/guns/porn. "The NSA/DEA-SOD has assured us this is a very bad guy, but all the evidence of that is non-admissible. So let's just 'parallel construct' another incriminating scene from what's handy."
