I wasn't aware that the Vic Police had active members from RMIT Uni specifically assigned to liasing with online forums, or that they subcontracted to graduate program members of Downer EDI Works.
Just giving you a friendly heads up that impersonating a police officer is a criminal offence, whether it be in person or electronically. If you wish to persist in these antics, then I will have no hesitations to contact your employer, uni and home ISP in addition to the police with reference to the posts you've made on these forums (they've all been archived and logged).
If however you do wish to post as a representative of the Police on these forums, I can provide you with contact details, to have a letter in writing sent to, from your Media Unit to authorise your drivel and inflammatory remarks as official statements on their behalf.
