Suppose some doped-up burglar tries your door, finds it locked, and leaves behind traces of drugs on the knob? You report an attempted burglary, the cops test the knob, and you get arrested? This lowers my respect for the cops a little more, and it was pretty low to start with.

No one was arrested because trace drugs were on the doorknob. A search warrant was obtained in part because trace drugs were found on the doorknob. From the article, "Kimball also decided there was enough other evidence, without the test results, to provide probable cause for a search warrant."

The doorknob was only a peice of the compelling information that convinced a judge to issue a search warrant. The perp was arrested after a properly executed search turned up illegal drugs.
