As an ex cop who also was busted while on the job, actually tested positive, the simplest answer is to get the shit out of your house. If this guy comes through for the police then depending on the judge they may very well be able to get a warrant for your residence. Unlikely? yes. Possibility? also yes. If you don't get it out, then I guess you'll have no choice but to remain paranoid for awhile. For those curious, my punishment, never to be a cop in this state again as noone will touch me.
