let's look at this;
somebody told the police you were making or selling drugs
the police found precusers for some illegal drug in the trash near your trashcans.
=============
well, maybe they watched you put the unidentifiable trash there. Maybe they did find fingerprints on something there since they do have them on record from your prior arrests.
Without any more info, you don;t know if they had probable cause to seek a search warrant or not.
I guess you'll have to ride this one a bit further to find out.
