If Sergio Calderón did steal the iPhone5 and if Calderón did give permission for them to search his home and if the Apple employees found it not an San Francisco Police Department officer would that not make the evidence inadmissible since an SFPD officer didn't find it? Calderón could easily say in court he never had it and the Apple employees planted it there.
